Nov. 16, .1928 THE GOLDEN TROUT OF THE SOUTHERN HIGH SIERRAS By BARTON WARREN EVERMANN Assistant in Charge of Di ;it 7 \i. m. The banks are lined with i);itches of small willows. The third cuiip was made in South Fork Meadows, southeast of Sand Meadow and about 7 miles from Camp .No. 2. The South Fork at this place is a very small stream, 2 to lo feet wide and a few inches deep, flowing usually with a slow current (about 3'J3 gallons per minute) over a bottom of coarse white sand, with here and there deeper pools, and at other places considerable riffles over boulders of various i in isonie respects* one of the most interesting streams in the Sierras. Its headwaters are among that group of stupendous mountain pealcs from Table Mountain (14,000 feet) in the Great Western Divide eastward through Mount Geneva, Crag Ericsson, Leland Stanford University Peak (14,103 feet), Junction Peak (1-4,000 feet). Mount Tvndali (14,101 feet), Mount Williamson (14,448 feet), Mounts Barnard, Tunnabora, and Wokorope to Mount Whitney (14,522 feet), the highest and greatest of them all. (PI. vi, figs. 14 and 1.5.) The course of the Kern is remarkable in that it is rectilinear and meridional, it being almost exactly due south for a distance ttf more than 28 miles, without wind- ings or curves of importance through the great Kern River Canyon, which for sublimity, as well as beauty of scenery, rivals the Yosemite. The direction of the canyon was, according to Professor Lawson, determined originally by a sti'aight rift which has controlled subsequent erosion, and the canyon Is therefore both a rift valley and an erosional trough. The Kern River is a considerable stream, carrying a large amount of water. At the ford just above Soda Spring the stream was on July 22 about 40 feet wide, with an average depth of 18 inches and a strong current. The water was clear and cold. The total length of this river is probably 120 to 150 miles, and the entire portion lying above the foothills of the Sierras is good trout water. The tributary streams are many. Those of importance on the west, beginning at the north, are Milestone Creek, Kern-Kaweah River, Chagoopa Creek, Funston Creek, The Big Arroyo, Rattlesnake Creek, Laurel C'reek, Coyote Creek, and Little Kern River; those on the east, from north to south, are Tyndall Creek, East Fork of Kern River, Whitney Creek, Rock Creek, Volcano Creek, Nine Mile Creek, Monache Creek, and South Fork of Kern River. The only ones of these examined during the present investigations were Little Kern River (and certain of its tributa- ries), Coyote Creek, AVhitney Creek, Rock Creek (and Guyot and Siberian Outpost creeks, two of its tributaries). Volcano Creek, and Soutli Fork of Kern River. Kern Lake. — Just below Soda Spring and the mouth of Volcano Creek is an enlargement or widening in Kern River known as Kern Lake. This lake was formed in the spring of 18t3S by a landslide or, more properly, by the washing of a large amount of debris from a small canyon on the east side and depositing it in the canyon of the Kern across the stream and completely daunning it. The dam is now triangular in shape and extends out from the east wall of the canyon. It is about an acre in extent, and most of it was not more than 4 or 5 feet above the sur- face of the lake at the time of our visit. The dam appears to have raised the water at least 10 feet, as shown by stumps of trees standing in water 10 feet deep. Most of these trees have been broken off at the water level, l)ut se\eral still project 1 to 10 or 15 feet altove it. The lake is about a mile long and half a mile wide. The deepest water is at the lower or south end on the east side, where it reaches a maxi- nunn of 13 feet. Three soundings taken near the lower end gave 8, 8.5, and 10 feet; a series of six at the lower end of the lake just west of the outlet gave 10.5, 10.5, 10.5, 10.5, 10.5, 11, and 11.5 feet; and another series just east of the outlet gave 11, and 12 feet. 8 BULLETIN OF THp; BUREAU OF FISRERIES. The strciiin has cut its way through the west end of the daui. The upper end of the lake is silting up rapidly, and it is a matter of but a f(iw years until the lake as -such will have entirely disappeared. The sand delta is now extending out into the lake in a series of ringers, with intervening channels, and the basin is already about halfway silted up. Upon this delta at the upper end is a thick growth of young cotton woods and willows. The greater part of this silted-up area is only a few inches al)ove the surface of the water, and the water in the channels through it is only 18 inches or less in depth. The depth over a greater part of the lake is 6 to 10 feet, and there is a dense growth of acjuatic vegetation covering nearly all the lake from the sand bars to the dam. This consists mostly of a species of /'nfiniiof/efon, a Bat)-ac/uu/ii, and various rilamentous algse. The white water crowfoot {H. frlcho- phyllmn) is the most abundant species and covers the surface where the water is not over 5 or 6 feet deep. In the lower end of the lake on the west side a large number of logs have accumulated in sluggish water, forming a considerable jam, as well as a favtyite resort for the numerous suckers that inha])it the lake. The river for about three-fourths of a mile below the lake is deep and sluggish, the depth being perhaps 6 to 10 feet. (PI. iv, figs. 7 and 8, pi. v, tigs. 10 and 11.) About half a mile below Kern Lake is a smaller similar lake, known as " Little Lake " or " Lower Kern Lake," which is said to have had a similar l>ut earlier origin. (PI. XIII, rig. 30.) It is about half a mile in diameter and is separated from the river by a levee of sand and silt on its east side, the river flowing a straight course at the base of the east wall of the canyon. The outlet of the lake is a small Vivulet, which cuts the levee at its southern end. Litth' Kern Rirer. — This stream lias its rise on the east and south slopes of Mount Vandever and Mount Florence at Farewell (rap. Hows southeast for about ^0 miles, and joins the main Kern River south of Trout Meadow. The greater portion of its course is through a considerable canyon, and the total descent is several thou- sand feet. The stream was examined by us from its source down to the crossing of the Hockett trail just below the mouth of Wet Meadow Creek. The stream is made up of a succession of falls, cascades, and rapids, with occasional more quiet reaches between. The majority of the falls would not seriously interfere with the free move- ment of trout, but there are at least two just below the Broder cabin which rish can not now ascend. The stream, however, has trout throughout its entire course and doubtless became stocked before the falls wore down to their present proportions. Above the crossing of the Hockett trail the Little Kern is a poor trout stream until the falls are reached. The bed is of gravel and the pools are shallow. The falls consist of a .series of steep slides and vertical falls, all close together, the total height being about 100 feet. No fall in this portion of the stream is sheer at high w-ater for more than 5 feet. A half mile above these falls are several others which individ- ually are as high as the rirst falls, but their combined height is less. Above the second falls the pools are larger and deeper and the stream is much better for trout. The fall of this creek is about 100 feet to the mile. At Broder"s cabin the volume was about 15,000 gallons per minute. (PI. iii, tigs. .5 and 6.) Wet Meadinn Creel: is a small western tributary of the Little Kern.

It rises on the divide just west of (^uinns Horse Camp, and flows southeast al)out 6 miles* before uniting with the Little Kern. Near its mouth it receives a small tributary from Pecks Canyon. Soda Creek at Quinns Horse Camp is much the same sort of a stream as the South Fork of the Kaweah at South Fork Meadows. It is perhaps a little more turbulent, but has, however, no iuipassal)lc falls. Trout are abundant. The distance from South Fork Meadows to Quinns Horse Camp is about 5 miles. The elevation of the summit of the pass between the two is »,()8U feet, as given on a United States Geological Survey bench mark. C'injofe C'rei'l: — This is a considerable stream, having its rise on the Western Divide between the main Kern and the Little Kern. Flowing east and southeast a distance of »> or 8 miles, it enters Kern River just below Soda Spring. Its upper course is through some small meadows, where the stream flows with a gentle current, but the greater portion is through a rugged canyon, in which the descent is very rapid and the stream verj' turbulent. In drops into Kern Canyon in a series of falls of considerable size and much beauty. The first (lowermost) of these falls is at the edge of Kern C'anyon and has a height of 19 feet. The channel of the stream is blocked bj' a huge boulder, around which the water pours, only a small amount creeping under the boulder. The second and third falls are a))out iJ5() feet above the first. The second is about 50 feet high; the third, or Broder Falls "*, 68 feet, and the distance between them about .50 feet. (PI. vii, figs. 17 and 18.) About one-half mile above the third falls is another, the fourth, which has a vertical descent of about 35 feet. Two hundred feet farther up is a fifth fall, with a drop of about 30 feet. (PI. VII, fig. lit, and pi. viii, fig. 20.) Among these various falls are excellent trout pools, and examples of trout were caught from each of them l)y some of the members of our party. Above the fifth falls are many others of smaller size, about and among which are numerous deep, relatively (juiet pools where trout may be found. As several of these falls now constitute barriers wholly eflective in preventing the further a-scent of fishes, it is evident that the trout had become distributed ihe full length of the stream before an\' of the falls tjccame impas8al)le. The trout of Coyote Creek show greater variation than is found among those of any other stream in this region. Those taken from below any one of the impas- sable falls can, as a whole, be distinguished from those above the falls, and it may well be that the efl'ects of isolation are beginning to show on the trout in the difl'ercnt parts of the stream. W/i/'i/iei/ Creek. — This creek has its sources in the snowbanks and tarns on the west and southern slopes of Mount Whitney, whence it flows a trifle south of west to Kern River. The total length is al)out 8 miles. At Cral)tree Meadow a small tril)- utary joins it from the south. Near the head of Whitney Creek are five considerablii little lakes or mountain tarns besides a dozen tin}- ones.

In the meadow it Hows with a good strong current. Its width here is about 12 to 15 feet and the depth 10 to 15 inches, with numerous deeper pools. The volume is about 7,320 gallons per minute. The bed of the stream in the meadow is clean white gravel with some black soil and decayed vegetation in the still places. Both above and below the meadow the bed is chieriy granite or granite gravel and boulders. About 1.5 miles below the meadow the stream drops about 200 feet in a close series of falls which fishes can not ascend. There is a l)eautiful cascade just below the meadow, l)ut it does not form an impassable barrier. From this point the stream descends rapidly in a series of picturesque rapids, cascades, and falls. Whitney Creek is the cleanest, clearest, and coldest of all the creeks we exam- ined, and, although an ideal trout stream, it is entirely without fish of anj^ kind. The lakes at its head (pi. ix. tigs. 23, 21, and 25) have an abundance of trout food, consisting chiefly of entomostraca and insect lairvse, and the larger ones should be stocked with trout. The stream also was found to be well supplied with fish food, particularly in Crabtree Meadow and other quiet reaches. (PI. x, tigs. 2(3 and 27.) Frogs were abundant all along the creek in all suitable places. The temperature of the water at Crabtree Meadow at 6 p. m. July 27 was 56°. Whitney Creek should be stocked with trout from Volcano Creek, and the transplanting could be easily accomplished. Bocl- Creek. — This creek has its various headwaters on the western slopes of Mount 'Le Conte, Old Mount Whitney, and Cirque Peak, and flows west to Kern River, which it enters about 5 or 6 miles south of the mouth of Whitney Creek. From the north it receives a small tributarj' called Guyot Creek, and from the meadows at Siberian Outpost (pi. vi, fig. 16, and pi. xiv, fig. 38) flows another some- what larger creek, which joins Rock Creek a mile above the mouth of Guj'ot Creek. (PI. XI, tig. 29.) All three of these creeks were examined, and no fish were found in them. They could be easily stocked either from Volcano Creek or the South Fork of the Kern. Volcano Oreeh."' — On account of the marvelously beautiful trout inhabiting its waters, if for no other reason. Volcano Creek merits a somewhat full descrip- tion. The course of the stream is peculiar. Its sources are on the slopes of Cirque Peak and among the other cirques of the south end of the High Sierras. A number of small streams come together in and above a series of broad grassy meadows south of Cirque Peak, forming Volcano Creek, which flows slightly west of south a distance of about 8 miles and then turns aVjruptly westward to pursue a more winding course for about 8 miles farther before joining Kern River opposite Soda Spring. The sources arc at an elevation of lo,o()() to 13,0((() feet. The upper course is through a succession of small moiHitain meadows, the larger ones formerly called " Whitney Meadows," but now known as "Volcano Meadows." Except in the more "This creek on some maps and elsewhere has been called Whitney Creek, a name applied to it when the mountain now called Sheep Mountain, or Old Mount Whitney, was thought to be the real Mount Whitney. When it was found that this stream does not rise near either Mount Whitney or Old Mount Whitney the name Whitney Creek was transferred to the stream described above under that name, and the name " Volcano Creek " Vas adopted for this stream. In some publications it has been called Golden Trout Creek. The United States Board on Geographic Names hasadopted the name Volcano Creek, which therefore becomes tlio recutfnized official name.

The total fall from the headwaters to the point where the stream turns west is between 1,<;00 and 2,000 feet. The bend to the westward is made just after the stream enters an east-and-west ancient trough or valle3' which Professor Lawson calls "Toowa Valle}," just below the most eastern of the series of small volcanoes or cinder cones which give name to the creek, and at a place known as the "tunnel." The elevation of the creek bed at this point is about 8.600 feet. The floor of Kern Canyon at the mouth of Volcano Creek is 6,300 feet. The drop made by this portion of the creek is therefore about 2,300 feet. (PI. x, fig. 28). As already stated, the descent made by the ci"eek above the '" tunnel" is without any considerable sheer falls. That portion below the " tunnel " is markedly difi'erent. Rapids, cascades, and sheer falls of large proportions and exceeding beauty follow each other in rapid succession, particularly in the last three or four miles. Only in (rroundhog Meadow and one or two other small meadows are any quiet reaches found. While there are many rapids and small cascades all along below the tunnel, it is only in the last three or four miles that falls of considerable size are found. A good general view of this portion of the creek is seen in plate viii, figure 21. Volcano Creek above the tunnel lias a bed of granite sand and gravel with granite boulders of various sizes from snrall to very large and in great profusion. From the tunnel to the mouth there is not so much granite, but nuich lava, volcanic tufa, and tufaceous sand. Though the stream for most of its course is turbulent and wild, there are three meadows of considerable size through which it flows more quietly. Here the banks are of sod or well covered by willows and other shrubs; the bed is of gravel of various sizes, fragments of lava, and finer material from the granite, lava, and soil. Below these meadows is the series of rapids and important falls already mentioned and which are more fully described on page 14. To understand Volcano Creek it is necessary to consider it in connection with another stream, the South Fork of the Kern. The relations of these two streams are peculiar and unusual. According to Professor Lawson, the South Fork of the Kern has its rise in the Summit Divide, about 3 miles southeast of Cirque Peak, flows southwest about 6 miles, and enters Toowa Vallej^ practically at the same point where Volcano Creek enters it. There it makes an acute bend to the eastward and flows southeasterly through the eastern part of Toowa Valley. (PI. XI, figs. 30 and 31.) At the point of nearest approach Volcano Creek and Soutli Fork of Kern are separated by a low alluvial ridge not over 75 or 80 yards wide at the level of the beds of the streams. The top of the ridge at tlie narrowest point is about 50 or 60 feet wide and not to exceed 30 feet above the streams. It is evident that these two streams were at one time tributaries of one stream which, according to I'rofessor Lawson, occupied the Toowa Valle}', and the separation of the drainage into two distinct streams, one flowing west and the other east in the same vallev, is an interesting problem which has its bearing upon the geomorphy of the region and, as well, upon the origin and relationshii^s of the trout of the two streams. 12 BULLETIN OF THE BUREAU OF FISHERIES. VokiiiK) Creek originally probably had its outlet to the westward through the same valley in which it now Hows. As Kern River cut its canyon deeper and deeper, Volcano Creek did the same, cutting back from Kern Canyon, however, only a mile or two, and doubtless forming considerable falls. During this time it is believed that the portion of South Fork of Kern above the tunnel was a triljutary of Volcano Creek. Subsequently the region through which Volcano Creek flows has been materially modified by flows of lava from several volcanoes which appeared on the floor of tiie valley or near it. Professor Lawson identified six such volcanic cones, at least four of which I was able to locate, one being on the left side of the South Fork just al)ove the tunnel. These small volcanoes sent streanis of lava in various directions, particularly down the gorge of Volcano Creek almost, to the bottom of Kern Canyon. This lava stream tilled the gorge of the lower part of Volcano Creek, which had been cut down nearly to the present Kern level. Above this gorge the stream has been variously obstructed by lava flows, one result of which has been to crowd the stream to the north and northeast sides of the valley. Another and very important result was the damming of the stream and causing the formation of a broad alluvial plain in the vicinity of the craters. Eventually this plain was carried so high as to make the di-ainage unstable, the streakn discharging sometimes by the Volcano Cr(>ek Valley, sometimes by the South Fork Valley, and dou))tless being sometimes divided l>etween the two. As Volcano Creek partially reopened its ancient channel by eroding the lava, the habit of the upper streams was finally changed, so that, instead of adding to the alluvial deposit, they began to excavate it; and when this change occurred it happened that the main branch of Volcano Creek discharged toward the west, while the eastern branch discharged eastward, constituting the present upper waters of the South Fork. The ridge between the two is merely a remnant of the alluvial deposit and is now only a few yards in width. Its narrowness suggested to certain ranchers living in the vallev of the South Fork the possil)ility of increasing, for irrigation purposes, the flow of water in the South Fork by tunneling the ridge. The level of Volcano Creek is slightly higher than that of the South Fork, and when the ditch or tunnel was made a por- tion of the water of Volcano Creek flowed into the South Fork. (PI. v, figs. 12 and 13.) Mr. George W. Stewart, agent of the United States Land Office, Visalia, Cal., has kindly furnished the following information concerning this tumicl: From the records of the board of supervisors of Tulare County, Cal., sitting as a board of water commissioners, I find there was presented to the board in 1883 a petition of Patrick Brady and 80 others to be allowed to divert from Whitney [Volcano] Creek at a point near a narrow ridge between Whitney [Volcano] Creek and Ramshaw Creek [South Fork of Kern] 4 miles below Whitney [Volcano] Meadows and 3 miles above Ramshaw Meadows 10,000 miner's inches of water under a 4-inch pressure, the same to be conveyed through a ditch and tunnel, the water to be used for stock, manufacturing, and irrigation, in township 26 south, ranges 33, 34, and 35 east. The said records show that niiiler date of ISeptember 13, 1883, it was ordered -" That prayer of said petitioners be granted and that they have out of said Whitney [Volcano] Creek, at said point of diversion, sufficient water to till their ditch — that is, 10,000 inches under 4-inth pressure." The tunnel was driven through a hill (ridge) composed mainly of disintegrated granite and., I have been informed, soon caved in, and was then transformed into what miners call an "open cut." This also caved in so that it had to be abandoned, and the water was diverted at a higher point on the stream, I believe, about U miles above. I have been told that the amount of water diverted through the tmmel was sufficient to permit the golden trout to escape into Ramshaw Creek. In 1899 when I FIG. 26.

Tlie flow of water was abundant for tlie purpose, and the water in the ditch, as I remember it, was not more tiian 3 feet below the surface of the water in the creek, and it flowed over a broad dam. The amount allowed to he diverted [10,000 miner's inches under 4-inch jiressure e(|uals 90,000 gallons per minute] was several times the whole volume of water in the creek during the summer months, and at thatiioint 1 doubt if it exceeded 10,000 inches many days in the year. It is not prol)- alile that 10,000 inches was diverted at any time, as it would he possible only during a freshet. Under the order granting the prayer of the petitioners they woullcanoes of the Toowa Valley and the upbuilding of their cones is later than that of the formation of the valley, and that they are features imposed upon, and independent of, the erosional geomorphy of the valley. The valley had evidently attained its present character, as far as erosion is concerned, before the volcanic eruption began, and has been but little modified since eruptive activity ceased, except l)y aggradation." The bed of Volcano Creek, however, has undergone considerable moditication since the lava How. This has consisted chiefl}' in the wearing away of the obstructing lava and in the formation of a niunber of considera})le falls in the last two or three 'Lafrson, op. oit., p. 321. 14 BULLETIN OF THK BUREAU OF FISHERIES. miles of the stream. This portion is vevy wild (pi. xiv, tig. :^lt), the total descent in the last 2 miles being about 1,600 feet. Starting at the mouth of the creek, the first fall of importance is found only a short distance back from the river. This is known as Agua-Bonita Falls, and the vertical descent is between 60 and 80 feet. (PI. xn, fig. 32.) A few rods farther up is a small but very beautiful fall (pi. xiii, fig. 34) with a sheer drop of about 10 feet, which I have named "Surby Falls."" About 300 yards above Agua-Bonita Falls is the second, or Stewart Falls'' (pi. xii, tig. 33), in a series of sheer drops totaling about 70 feet. The next or third important falls (pi. VIII, tig. 22) is several rods farther up stream, and has been named '"Shields Falls."'' It consists of two sheei' falls each of about 25 feet. Several I'ods above these are Twin Falls (pi. xiii, tig. 3.5), just below the crossing of tlie trail. These are very beautiful, and have a sheer drop of al)out IS feet. These four falls are each and all barriers that fishes can not possibly surmount. Fishes could, of course, go down over them and they doubtless do so, but they do not go out into Kern River. The trout of Volcano Creek are a small, creek-loving species, and evidently avoid the larger stream. The various falls are adequate in keeping Kern River trout from ascending Volcano Creek, and these same falls, together with the size of the stream, are ecjually adequate in keeping the creek trout from entering Kern River. The trout of Volcano Creek are therefore as completeU' isolated from those of Kern River as if a land barrier intervened. That Volcano Creek was originally stocked with trout from Kern River ma}' be accepted without much question. The lava flows already referred to doubtless killed off all the trout of the lower portions of the creek, leaving perhaps onl}- those of the headwaters to reinvade the depleted lower portion after the conditions became suit- able. At that time it is probable that the trout of South Fork of Kern (which was presumably also stocked from Kern River) did not materially differ from those of Volcano Creek; but the period that has elapsed since their segregation, due to the formation of the alluvial barrier and the numerous impassalde falls, has proved quite suthcient to permit a differentiation which renders them readily distinguishable and. I believe, specifically distinct. About one-half mile above Twin Falls a small stream from the .south enters Volcano Creek. Near its mouth this stream has cut its way through the volcanic tufa and formed a natural bridge (pi. xiv, fig. 37). This bridge is 18 to 20 feet wide, 12 to 15 feet high on the lower side, and 8 to 10 feet high on the upper side. Masses of this tufa are found in all the more (juiet reaches of Volcano Creek from the tunnel down, and in the eddies and deeper pools the bed is largely made up of this material, either as fragments of various sizes 6r as sand. The color of the tufa is a light lemon-yellow or yellowish white. The tufa seems to dissolve or break down readily in the water, the result being that the water is more or less milky. The similaritj' in the color of this tufa, and even the general color of the bed of the stream in many places, to certain colors found in the trout forces itself on one's attention.

It rises southeast of Cirque Peak on the east side of a high mountain ridge separating it from Voleano Creek. For tiie first six or seven miles its course is west of south until it enters Toowa Valle}' near the tunnel; there it turns abruptly to the southeast. After flowing through South Fork of Kern Meadows it turns southward, which course it follows for several miles, and then, turning west- ward, enters the main Keini River a few miles south of Keruville. The stream was examined by us only in that portion of its course easily reached from the tunnel. At that place it is smaller than Volcano Creek, hut below South Fork of Kern Meadows it becomes a considerable stream. At the lower end of these meadows it receives from the north a tributary known as "Mulk}' Creek," a small stream of special interest because of the fact that the trout with which Cottonwood Creek was originally stocked came from it. Cottonvyjod Creel-. — A few words should be said of the waters of the east side of the southern High Sierras. Numerous streams of greater or less impoi-tance having their headwaters on the eastern slopes of this range flow dinectly into Owens Lake or into its most important tributary, Owens River. Lone Pine Creek and Turtle Creek have their sources on the east side of Mount Whitney, Mount Le Conte, and Sheep Mountain, opposite Whitney and Rock creeks, and, flowing eastward about 14 miles, enter Owens River at Lone Pine. Cottonwood Creek rises on the eastern slopes of Sheep Mountain and Cirque Peak opposite the headwaters of Rock and Volcano creeks and flows southeast about 15 or IS miles to Owens Lake. Well toward the head of Cottonwood Creek are said to be some small lakes. All of these streams, so far as known, were originally without trout of any kind. Some of them, however, have been stocked. The cii'cumstanccs attending the stocking of Cottonwood Creek are explained elsewhere in this report (p. HH). THE FISHES OF THE KERN RIVER REGION. There are not many species of flshes in the Kern River region. Two species of suckers, three of minnows (Cyprinida^), and two of trout seem to be all that have been recorded. But the streams and lakes have not been carefully investigated and it is quite probable other species will be found when more thorough collections are made. Of the two suckers only one was obtained by us. Specimens of the three minnows were secured. As regards the trout, our collections contain more species than have hitherto been recorded from the region, there being at least six represented. They are all save one I'egarded as belonging to the rainbow trout series and are as follows: (1) the Kern River trout {Snlmo gilhert!)., occurring only in Kern River; (2) S(ihfu) agua-hinJta, native only to the South Fork of the Kern and its tributa- ries, but introduced from it into Cottonwood Creek; (.3) the golden trout of Volcano Creek, which does not occur in any other stream; (4) the Soda Creek trout, found throughout the basin of the Little Kern and in Coyote Creek and introduced from Soda Creek into the headwaters of the South Fork of the Kaweah; (5) the common rainbow trout {Snlmo sliuxtd)., widely introduced by the state flsh commis- sion into the waters of the state and found by us in the headwaters of the Middle Tule, the lower course of the South Fork of the Kaweah, the Middle Fork of the 16 BULLETIN OF THE BUREAU OF FISHERIES.

We saw it at all the fords, and specimens were ol)tained from North Fork at Redstone Park and from Middle and South forks near Threerivers. They wej'c caught with worms, artificial fly, and trolling spoon. Though they would rise to the fly they preferred worms, which they devoured ravenously. One of our party took with the spoon several large examples, one 2 feet long, weighing pounds. Another, taken July 13 by Britten Brothers f I'om the main Kaweah, was 28 inches long and weighed 7.25 pounds. It was a female full of nearly ri[)e eggs. The larger examples of this species are (juite game and make a very good tight. With the preceding this also is locally called "lake fish" or "lake ti'out." The ])('ople of this region, however, seemed to know vei'v little al)out these tishes. They consider them bony and randy eat them. 5. Rutilus symmetricus (Baird iSc (iirard).

The two smaller speci- mens have the tip of the lower jaw hardened into a horny sharp edge. The largest specimen shows onh' a remnant of this hardened edge. The species is found chiefly in shallow water. It takes the hook with a \im and will rise to the ai'titicial fly, but prefers worms. THE THOUT OK TIIE KEKN KIVEU REGION. The native trout of the Kei'u River region represent at least four well-marked species or subspecies, all belonging apparently to the rainl)ow-trout series. They are as follows: (1) The Kern River trout (Sn/i/i." tiUhcrti), occuri-ing only in Kern River and possibly in the lower portions of some of its larger tributaries. The tyi)c locality is Kern River at Soda Spring. This is the species from which it is believed all the other native trout of the Kern basin have descended. (2) The Soda Creek trout, native to Soda Creek, Wet Meadow Creek, Little Kern River, Coyote Creek, and possibly other small western tributaries of Kern River, and introduced from Soda Creek into the headwaters of the South Fork of the Kaweah at South Fork Meadows, and elsewhere. (3) The South Fork of Kern golden trout {Salmn ngna- hoiilfn)^ described originally from Cottonwood Creek, into which it had been introduced, but native only to the South Fork of the Kern and its tributaries. (4) The golden trout of Volcano Creek. This is the real "golden trout" and is native only to the one stream — Volcano Creek. B. B. F. Wib—-i 18 BULLETIN OK THK BUREAIT OF FISHERIES. Compariiio- the trout from these various .streiuus the followiiiustiitonients appear to be justitied: (1) Tlie Kerii Hivei- trout is piofusely and closely spotted o\cr the entire body. head, and on all the tins, and the belly is not richly colored. {)i) Tlie Soda Creek trout has nunierons black spots on iiead.

Another example, weighing 2 pounds, taken the same day at the lower end of Kern Lake, was described as follows: Color on liack and upjxM- thiixl of sitle very BULL. U. S. B.

Another example (a male IS inch(>s lono), caught l)v one of our party in Kern River above the lake, had top of head, back, and entire side closely covered with small roundish l)lack spots, similar spots coverino- vertical tins and some on pectorals and ventrals; cheek and opercles dark rosy, with a few ))lack spots; general color dark olivaceous; side with modei'ately distinct rosy liand. This species is abundant in Kern Lake and in the river for several miles above the lake. It is prol>al)ly common in the river for some miles below the lake, but of this I lia\'e no personal knowledge, as we did no collecting below the lake. As a rule, the tish taken from the liver are more deeply and l)i'ightly colored and decidedly more game than those from the lake. During the spawning season early in the spi'ing the fish are found ehiefl}' in the river, but after the spawning has been (■ompleted they tend to run down into the lake, where they become less active and less liighly colored. The large examples which we took in the lake were, as a rule, more slender than those from the river, pi-obably on account of the fact that those from the lake were all spent fish. This species is said l)v •Fordan and Kvciinann" to rea<'h a W(>ight of S jiounds^ but I do not recall the authority upon which the statement was based. The largest example seen by us was the one upon which the above description is basetl. It was Is. '25 inches long and weighed 8. .5 pounds. Several othei- examples L-t to lit. 25 '' inches long were caught by us. The largest individual of which I have a definite record was caught in 1900 in the river above the lake by Mi'. E. I). Cox and weighed byMr I). J. Cruice, both of Bakersfield, Cal. This fish was 27.5 inches long and weighed 5 pounds 11- ounces. The Kern River trout is a beautiful lisli. well l)uilt and synunetrical, and very rich in coloration when in prime condition. As a game fish it will stand easily among tlu! best, ])ut, as already stated, in the river it greatly exc^els those of its kind in the lake. It usually takes the i\y ((uite freely, and will, of course, take all sorts of live or rut bait. Members of our party took these trout with the aiiificial fiy, with grass- liopp(>rs (which they greatly preferred), and with pi(H-es of fish or other meat. The large example painted was first tried with a gray hackle, to which he rose once and then paid no more attention to it. A larger, ]>lain hook and a good-sized grass- ho])per were substituted, with better results. Scarcely had the lure touched the water wdien ho rose and struck most viciously, only to miss it, then turn and strike again more viciously than before. This time the hook caught inside the mouth just under the middle of the maxillary, and then began a fight that would delight a better " Kishes North and Middle America, j). 502. ^ AltlloUKh ttie longest fiyh ciiu^ht by us, lhi.s was a slender indiviilual w fi;;liinti under :i pounds. 2'> HILLKTIN OF THK HUREAr' OF FISHKRIKS. aiiylci' than I.

Another o()od-sized example (2 pounds) was taken July lit at the drift in the lower end of the lake. This fish was seen swinmiint;- slowly down the lake at a deptli of about 3 feet. A cast l)i-oui,dit a rise at onci*. Missinji', he turned and came again, not with a rush, but deliberately, ami took the lure. He pulled and tugged vigor- ously, rushed a bit. junqied once, shaking his head savagely, ran inshore then out again. Then I reeled him in. but three times he dashed away before 1 could use the landing net. This was the gnmes( lish caught in the lake, and was not much inferior to those taken in the liver. Another larg(M'xample caught in the lake .Inly 20 broke watci' six times licfore coming tn net. ami was really \erv game. Trout appear to be (piite abundant in Kern Hi\('r. but it is doubtful whether they will long remain so. During the few days we were at Kern Lake, six or seven other parties were lamped at or near the lake, each party consisting of from two to t(>n people. ( )ne party of two. excellent anglers and ti'ue sportsmen, had been there for more than two months. They tished more or less ev(M'y day, always with the Hy, and usually threw bacdv all they caught, especially the smaller ones. Another party of two W(>re observed to go out upon the lake every day, tie their dugout to a snag, and devote the entire day to jerking out the trout. They kept it up day after daj', and none wa.s too small for their ci-eel. On one o('casioii they were noticed to have at least 3() fish (! to 12 inches lont;'. And most of the other parties wei'e doing about the siime. At this I'ate the trout can not long continue abundant in this stream. All tishiug in the lake should be prohibited, the daily catch from the river should be limited to 10 tish per rod, and 8 inches should be the minimum legal size. This species was named for Dr. Charles H. Ciilbert, professor of zoology in Stanford University, who collected the type July 13, IS'.tS, from Kern River at Soda Spring.

In spirits all the l)right colors have faded, but the l)Iack spots remain distinct. These spots are largest on the caudal peduncle, over which they are evenly distributed. They are also pretty evenly distributed over the entire side and top of head; the space along the lateral line, however, has fewer spots. Those below the lateral line extend more than halfway to the belly and are somewhat smallei' than thos(^ above. About fourteen spots show on side of head. There is not much variation in color, as shown l)y examination of many exam})les. In all, the black spots completely cover the caudal peduncle and the entire length of side from median line of hack to some distance below the lateral line; the top and sides of the head are alwaj's spotted. The middlt^ line of the side and the l)elly are always richly colored, the parr-marks always present, and the dorsal, anal, and ventral fins bright-edged. No conspicuous red dash was observed on the lower jaw in any of the specimens from South Fork of Kaweah, Soda Creek, or Wet Meadow Creek, hut among those from Coyote Creek were some showing considerable color. \ cotype was described as follows: Back and top of head light brown with numer- ous small black spots extending on dorsal and caudal fins and on side distinctly to lateral line and below it less plainly, those on caudal peduncle largest and blackest; black spots also on top of head and halfway' down sides on opercles and cheek; middle of side with a broad red or orange-red band extending from just behind base of pectoral to about middle of anal, l)roadest in middle portion; a largo blotch of same color on opercle and some on cheek; thirteen distinct parr-marks on side, a row of smaller similar spots below; lower part of side light brown; a broad reddish or oi'ange Ijand along ventral line from throat to vent, the antei'ior part yellowish; dorsal Hn covered with small hlack spots except anterior upper margin, whi(^h is light pink, whole distal edge, except the pink, margined witii black, not (pate continuous; pectoral olivaceous, with pink tinge, overlaid with dusky; venti'als same color as pectorals, but the piidv more pronouni'ed and the exterior distal edge white; anal same as ventral, bordered with white; caudal spotted like the dorsal, but no pink edge; adipose same as hack, margin hlack, one spot on base.

The collection contains It) specimens from the South Fork of the Kaweali Ri\-ei' at South Fork Meadows and ?> from Soda Creek at Quinns Horse Caui]), about ."> miles distant. Besides these specimens, we examined perhaps 2.5 others from those two places. They range in length from 5.5 to 7.75 inches and are quite unifoi-m in size. They show little or no mori^ variation in cokir than is indicated by the pre- ceding descriptions. The collection al.so contains five specimens from Wet Meadow Creek, which are in some respects the finest that were ol)tained. They range in length from 7 to 9.75 inches and show some variation in spotting. The smallest two of these ai'e more sparsely spotted than any of the others; nevertheless they show spots the full length of the side and some spots l)elow the lateral line. The largest specimen (cotype No. 53398, U. S. N. M., 9.75 inches long) is rather mon; completely spotted than the type. The two other Wet Meadow Creek specimens (cotypcs), although lajgcr than the type, ai-e .spotted very much like it. A large number of examples were examined from Little Kern, taken chieHy in the vicinity of Hroder's cabin: of these, three were saved. Th(\y agret^ in all respects with those from South Fork Meadows. Forty-four excellent specimens were obtained from Coyote Creek. These wer(> taken at various places between the headwaters and the mouth of the stream. This creek has several falls which doubtless at present are barriers to the ascent of tish; nevertheless trout are found throughout the entire length of the stream, and are abundant immediately below and al)0ve each of the falls. Evidently the peopling of the entire stream was accomplished before the falls were formed or became impass- able barriers. An examination of the large series of specimens shows them to be a very perplexing lot; the amount of variation among them is very great, and it is not without hesitation that I refer them all provisionall_y to Sahiio vh'ttei. In general they all agree essentially in being well spotted, although occasionally a s)K'cimen is seen with fewer spots below the lateral line. The spots, however, vary considerably in size; in some they are larger than in the South Fork Meadows tish, in others they are smaller; in many the spotting is more complete. In life some examples were (|uite dark in general coloration, and several showed red or yellow between the rami of the lower jaw. An eti'ort was made to see whether these difterences could be cor- related in any way with different particular parts of the stream, and there is consider- able evidence that such correlation can t)e made. It is believed that all the specimens taken between any two falls agree better among themselves than they do with those from any other portion of the stream, and it seems that we have here a numlier of differentiations now in progress which promise to become of taxonomic value. For the present these trout are all considered to be conspecitic with those from South Fork Meadows and Soda Creek.

Of my H'.i specimens all but 5 are more or less profusely spotted above the lateral line along the entire hnigth of the side and on top of head and snout. In the National Museum are 2 specnmens (No. -Kil20), collected in Cottonwood Creek (into which the species was introduced from South Fork of Kern) September 12, 1S91, by Basil Hicks Dutcher for the Biological Survey, Department of Agricul- ture. These specimens are 0.5 and 7 inches long. The smaller one still shows a numbei- of dark spots along side above the lateral line at least as far forward as the beginning of the dorsal. In the other the spots have faded and are not distinct except on the caudal peduncle. Two other specimens (No. 4(!li!l)are in the National Museum, collected in 1891 by Mr. F. Stephens, also for the Biological Survey, in the South Fork of the Kern at about 6,5(H» feet altitude. They are 4.5 and f!.25 inches long, and each is profusely spotted above the latei-al line for entire length of body and on snout and top of head. The first record of trout from this poi-tion of the Sierras is that by Jordan and I Henshaw in the Report of the Chief of Engineers of the Army, for 1878. In this report a single specimen (No. 17107, U. S. Nat. Mus.) is recorded. It was caught in 1875 by Mr. H. W. Henshaw from the South Fork of Kern River, Kern County, Cal., and was identified as Sdlmo irideux. Not until seventeen years later did other specimens from this locality c^ome into the hands of any ichthyologist. In 18!»2 Dr. David S. Jordan received three small ti'out from Mr. W. II. Shockley, of San Francisco, to whom they had been sent by THK GOLDEN TKoUT. 25 Mr. (Teorg-f T. Mills, stutt' tisii coiiimissioiu'i- of Nfvadii, who hiid roccivcd thmii troni Mr. A. C.

The nienioranduni awoni- panyino- the specimens when they came into Dr. Jordan'.s possession was to the eliect that the fish had l)een "taken by Mr. Harvey, of Lone Pine, Cal., in a stream called by him * Whitney Creek ' (more correctly Volcano Creek), on the west side of the Sierras neai' Mount Whitney." Dr. Jordan described these specimens as a new subspecies uikI(M- the name Saliiio myl-isx iKjiKi-honltd in the Proceeding's of the L'^. 8. National Museum for 1892", pag;e 4-81. In 1891 members of the Death Valley F^xpedition of the C S. Biulooical Survey collected a luimber of trout in this reg;ion, as follows: Mr. Vernt)n Bailey, 2 specimens from Volcano Creek in Whitney (Volcano) Meadows; Mr. Y. Stevens, 2 specimens from South Fork of Kern River, and Mr. B. H. Dutclier, 2 specimens from Cotton- wood Creek. These were examined by Dr. Chas. H. Gilbert, who repoi'ted on them in North American Fauna No. 7 as Salmo uii/k/vs agiia-honita. Ill the sunnner of 1893 Dr. Gilbert visited the Kern River region and obtained specimens of trout from Kern River at Soda Spring and from Volcano Creek. The former were described l)y Dr. Jordan in 189-4 as Sa/mu (jairdiH'ri ililhui}.'' It has since developed that the specimens sent to Dr. Jordan liy Mr. Sbockley, antl upon which Dr. .lordan based his description of Saliita mi/kisx e at its lowest \'alne. The clianu'ter of the hottom and water itself has mneh to ilo with this, and I remeuil)er lo have tished ill a small rivulet on one of the snbalpine meadows not far from Mount Whitney, whose shi;;- ffish waters flowed over a bottom of dark mud, in which the color of the trout simulated very closely its hue; they had lost nearly all the flashiny; iridescent tints characterizing the same species caught hut a few hours before in another stream, and had become dull and .'Jomber-hued. Accompanying this change of color was a correspondingly noticeable difference in habits and motions, and the several dozen trout caught that evening for supi)er were taken out by the hook with the display of very little more gameness than would be noticed in so many horned jiout. ()n tlie contrary, in the clear, rai)id current of the mountain stream a flash of sunlight is si-arcely quicker than the gleam of gold and silver seen for a single instant as the whirling waters are cut by one of these trout as he makes a rush from his lurking place for some chance morsel which is being Iwrne past him. The western trout are rarely as shy as their relatives of eastern waters, and because of their mmdjers and the consequent scarcity of food are apt to he less fastidious; yet, even when most abundant, due caution must be used if one w'ould be successful, and not every one can catch trout, even in the West. With the jiroper care in concealing oneself, a |iool may be almost decimated ere the alarm will be taken, and 1 have seen 15 fair-sizeil trout taken from a single small pool in quick succession.

There is not much variation in color, except such as is probal)ly due to dilference in age; the rosy lateral band, the pari'-marks, and the broad rich cadmium \nu\d on the belly are characteristic. The variation in the black spots is inconsiderable. In the 2!' specimens which 1 have examined critically 15 do not show any spots whatever anterior to the adipose tin, and only '2 of the remaining 1-1 show any spots anterior to the dorsal fin, and these are obscure and few in num))er. In one large specimen there are but 12 to 1-t spots on the caudal jjeduncle; in another somewhat smaller example there are !)ut (i spots. 'rh(> dorsal, anal, and ventral tins are invarial)lv edg(>d with brighter color. Tlu' lieavery pool at tiie foot of a fall or below a cascade or rapid was .'•ure to contain a number of them, and others were seen on the riffles and under the protecting l)anks. They were most numerous above the tunnel. proba))ly because fewer tourists visit that portion of the stream. The fish tiiere, however, were usually small. The largest, finest examples were seen between the natural bridge and the lower falls. As a game fish the goklen trout is one of the best. It will rise to any kind of lure, including the artificial Hy, and at any time of day. A No. 10 fi3' is large enough, perhaps too large; No. \'l or even smaller is much lietter. In the morning tuid again in the evening it would take the fl>' with a rush and make a good tight, jumping fretiuently when permitted to do so; during the middle of the day it rose more deliberately and could sometimes be tempted only with grasshoppers. It is a tish that does not give up soon but continues the tight. Its unusual breadth of tins and strength of caudal peduncle, together with the turbulent water in which it dwells, enable it to make a tight equaling that otlered b}' many a larger trout. Although now abundant the golden trout can not long remain so unless afforded some protection. The attractiveness of the Kern River region because of its scenic beauty is sure to appeal more and more to tourists eveiy year. Practically the entire length of Volcano Creek is easily accessible from the trail from Kern River to Mount Whitney, and that portion above the tunnel is covered by the trail from the east side of the divide. As a matter of fact one can in one day travel the entire length of the creek and have time to stop frequently to drop a Hj- into the pools which he passes. The trout are readily found and are easily captured, as they are so voracious and rise to the lure so readily. Two years ago the mem))ers of the Sierra Club and others accompanying them on their annual outing to Mount Whitney are THK fiOI.DKN TRply cost us these fish. We hope this coming summer to send one of our experienced men into the Whitney Creek region to collect as many four-inch to six-inch trout as we can, transport them to Sis- son, and place them in our hatchery ponds to be used as breeders. In the spring of 1905 Mr. Earl L. Morris, of Stanford University, visited Cot- tonwood Creek and caught with hook and line and seine 50 trout, which he took without loss to San Francisco, where they were exhibited for several weeks at the Exposition of the Pacific P^ish and Game Association. They were then transferred without a fatalitj' to the Sisson hatchery, where they will be propagated by the Califoinia fish commission. This is the South Fork of Kern trout, but it is probabl}' no more hardy than the Volcano Creek species. In Ma3% l!t05, the United States Bureau of Fisheries attempted to establish a temporary station on Vok^ano Creek for the purpose of taking the eggs of the golden trout. It was found that the spawning season was practically over before the station could })e installed, and the matter was postponed temporarily. A number of fish (2t)-lr) were captured, however, and carried practicallj' without loss on pack animals to Lone Pine, whence they were shipped in care of a special messenger to the Lewis and Clark Exposition at Portland. Through a mishap, however, the entu-e lot was lost en route. Although the efforts thus far made have not proved successful, it is not believed that any real difficulties exist to prevent the carrying of trout from Volcano Creek to one or more of the trout hatcheries of the Bureau, and it is hoped that another efibrt may soon be made. If a number of fish can once be gotten to one of the hatcheries it will be easy to propagate the species artificially. There are many small mountain streams in the Western States where this fish would certainly thrive. It should also be tried in certain streams in the East.

It would be extremely interesting to try the species in several streams and note the effects of the new environment. The possihilit}' of add- ing siu-li an attractive fish to the streams of other states is well worth a serious (effort. It is also desirable to establish a temporary hatchei-y ggs may be taken and eyed for shipment. Another thing that should be taken up at once, preferably i)y the California tish commission, is the stocking of barren waters in tlie Kern River region. As state(l elsewhere in this report, there arc inaii}' small streams and lakes of the southern High Sierras that are entirely without fish of any kind, although certainly well suited to trout. Among these may be mentioned Rock Creek, Guj^ot Creek, Whitney Creek and the lakes at its head, and many others. To stock these waters by transplanting from Volcano Creek would be a very easy matter. /'rofect/(i/i. —Afi already stated, it is only a (|uestion of time, a very few years at most, when the golden trout of Volcano Creek will become practically exterminated unless it receives some j)rotection. In order that ad(H[uate protection be secured, it is recounnended that the limits of the Mount Whitney Military Reservation be extended so as to include the whole of Volcano Creek. This can be (U)ne liy extending the eastern botmdary from the pi'esent southei-n boundary along the meridian of 118-10' to its intersection with th(? parallel of 86 20', thence west on that yjarallel to Kern River, which should be made the western boundary. The northern boundary should be extended westward to the main fork of Kern River. This would include all of Volcano Creek, the head- waters of Cottonwood Creek, and South Fork of the Kern, as well as all of Rock Creek and Whitney Creek. When the boundaries have been thus extended, fishing within the limits of the reservation should be absolutely prohibited for three years, after which it might be permitted under certain restrictions. These restrictions should provide a minimum size, limit the num))(>r that may he. caught, and prohibit •ill fishing during the sjjawning season. \Vith such regulations as these, together with the tisli-cultural opei-atioiis sug- gested, it is bebeved the golden trout will continue- an abundant tish and remain one of the great attractions of this interesting region. lo. Salmo Shasta Jordan. S/insfii Tnnit ; Ruiiilxiir Trout. This is the common rambow trout of tish culturists, which has been introduced into luany difi'erent waters in southern California. Specimens of a trout which we provisionally identify with this species were obtained at the following places: South Fork of Kaweah River 4 miles above Threern'ers, and at AUes's ranch about -1 miles farther up; Middle Fork of Tiile River in its iieadwaters; Middle Fork of Kaweah River just ))elow the new powerhouse, or about 1.5 miles below the mouth of the East Fork: and in Mail)li' Fork of Kaweah above the bridge on the road to the Giant Forest. The following life-color notes were madr by Hr. Jenkins on specimens obtained by him from Marble Fork: Specimen F: Dark olivaceous above to white on belly; no sign of color i)and on belly; color band on side brick red, narrow, brightest in center of bod}' and indis- tinct at the extremities; opercle and preopercle indistinct reddish, also marks on THE GOLDEN TROUT. 31 throat light A'ellowish. not conspicuous: body covered with many rather large spots which extend nearly to helly; dorsal with dark spots irregularly placed; tips of about first (3 rays yellowish white; caudal spotted irregularly; pectoral dusky, with outer portions showing yellow; ventrals pinkish, with anterior margin white; anal reddisli, tips of about 5 anterior rays white. Specimen G: Like ])receding, except much lighter in general color; color band very faint; marks on throat almost ol)s(>lete; pectoral pale yellowish; venti'als pinkish with white tips; anal dusky, faint pink, with margin of white; spots on dorsal slight, show of white on tips. Specimen H: Similar to preceding in lightness of color, being light gray; spots on l)ody, top, and sides numerous and distinct; color band on side of body and color on opercles very indistinct; throat mark not distinguishable. Specimen I: Light gray spots nuinei-ous, small — few below lateral line; reddish band, throat marks, and color on opercles distinct; tins as in the preceding. Specimen J: Light gray, passing to white on lower sides and belly; reddisli band evident, but indistinct in extent; reddish on opercles; throat marks conspicuous, reddish orange; no spots on body; spots on dorsal, but few on caudal; pectoral faint yellowish; ventrals pinkisli with white tips; anal faintl3' dusky with white tips. Specimen K: Similar to above, but with few spots. Six examples taken from the South Fork above Threerivers were in alcohol pro- fusely spotted on the caudal peduncle, on side above lateral line, and usually on top of head with small irregular stellate black spots, quite different in shape from those found on the trout from South Fork Meadows. The Threerivers trout also seem to have a shorter head. Their life color was (piite different, being much less brilliant. An example caught at Alles's ranch showed side with a broad red or rosy band; (jpcrcle rosy; back and side above lateral line profusely and closely spotted; few spot.s on side below lateral line; nine parr-marks; dorsal with many round l)lack si)ots, the anterior edge of tin rosy; pectoral yellowish; ventral and anal dull red, edged with white; no red on throat. Twelve other trout were obtained at this place. They ranged in length from 5.5 to 8 inches and agreed essentially in coloi's. Most of them were somewhat silvery, but all showed the rosy lateral band, the parr-marks, and the white or ^^ellowish tips to the dorsal, anal, and ventral tins. Examples taken bj- Profes.sor (xreen in Middle Tule were described as follows: Back dark olivaceous or bluish; back and side covered with rather large roundish black spots, few and small in front of dorsal; spots on side extending to belly on nearly all; median line of side with a narrow i)and of light brick-red (not so bright nor so wide as in Soda Creek fish) from middle of pectoral to middle of anal, some- times farther back; cheek with dusky brassy; operde red above, paler Ixilow, with dusky wash; ))elly white, sometimes dirty white, no orange or red; pectoral yellow- ish; ventral dusky yellow, edged with white; dorsal same as back, with S or 4 rows of spots, anterior distal edge creamy white with some orange; margin black; caudal with fewer spots than South P^ork of Kaweah trout; anal pale, with a few small spots on base; white-edged; adipose fin margined with black. Another example 8.25 inches long was described as follows: Spots on caudal same as dorsal; no red on lowei' jaw; blotches of immature trout plain; anterior half of dorsal edged with yellowish white; first ray and tips of 3 or -i anterior rays of fins 32 HULLETIN OK THE lUIRKAU OF FISHERIES. niari;iiicd with white; pectoral yellowish; aiitcrior half of ventral ;iiul anal tins n^d- dish; adipose tin inuri>ined with black; side not silvei-y except in siiiall indiviiluuls. hut irregularly blotched with color similar to immature markings; latend band not con- tinuous, but broken by blotches on immature examj)le and not extending to caudal or to cheek; color of band light brick red. lighter red on cheeks. In alcohol these trout closely resemble those from South Fork Meadows. The spots, however, ajjpear to be rather larger and less regular in form. They differ from the Threerivers trout in being decidedly more spotted below the lateral line; the spots, how-ever, are of the same shape in these two groups. In life these Tule trout resemitled the South Fork Meadow trout in their bright coloration, but it was noticed then that the l)lack spots were different in shape. The !) examples caught in Middle Tule ranged from 5.75 to 9 inches in total length, and closely resemble those taken in Middle Fork of Kaweah aliove Threerivers. II. Salmo clarkii Kichai-dson.

INTRODUCTION OF TROUT INTO STREAMS OF THE SOUTHERN HIGH SIERRAS. During the last twenty -five or thirty years connuendable interest and activit}' have been shown by the citizens of Tulare Count}' in conserving the supply of food and game fishes of their portion of the state. This activity has manifested itself in securing consignments of trout and other species from the state and federal govern- ments and in transplanting native trout to barren waters. This excellent work has been brought about through various agencies. In the first place, a rancher, observing that certain streams, apparently well suited to trout, were wholly without fishes of any kind, would undertake to stock the barren stream by ti'ansplanting trout from some near-by waters. The eiiuipment for the work, though usually ([uite primitive — prob- ably consisting merely of a tin can, a coffeepot, or bucket — was often adequate, and THE GDLDEN TROI^T. 33 tlie tiiiiisplitiiting WHS successfully uccoiiiplished. Mr. John Broder, of Rcd.stonc Park, has been very active in stocking barren waters of this region, and he informs me that to his knowledge the following streams have l)een stocked with trout in recent years: East Fork of Kaweah throughout its entire length and including several of the small tributaries at its headwaters; Cliff Creek, tributary to Middle Fork of Kaweah, just north of Mineral King; Wolverton Creek, tributary to Marble Fork of Kaweah at noilh edge of the (Jiant Forest; Big Arroyo, tributary to Kern lliver, stocked by Edward Hurlburt from the Little Kern; Rattlesnake Crei'k, tritnitai'v to Kern River, stocked by Mr. Broder from the Little Kern, the result not known; Shotgun Creek, one of the headwaters of the Little Kern; Nine Mile Creek, an eastern tributary of Kern River which it joins below Kern Lake, was stocked from Kern River in 1897 by Mr. Broder near the Hot Springs; South Fork of Kaweah at South Fork Meadows south of Sand Meadow with trout from Soda Creek at Quinns Horse Camp. The history of the introduction of trout into Cottonwood (]reek and the subse- quent description of the species is interesting and should be made a matter of record. Cottonwood Creek was originally without trout of any kind. Desiring to learn the facts concerning the introduction of the fish into this stream I interviewed or wrote to a number of gentlemen who were supposed to possess information bearing upon the tuansai'tion. In response to my letters several replies were received. Judge A. C. Harvey, of Lone Pine, Inyo County, Cal., gave a full account of the transplanting. He says: The golden trout were caught in South Fork of Kern River in a little stream in Mulky Meadow, just where the Hockett trail enters the meadow. They were caught with liook and line by S. V. Stevens, A. C. Stevens, and Thomas George. Thirteen fish were (taught antl carried in a coffee pot over the Hockett trail and put in Cottonwood Creek about a ndle above the Stevens sawmill, at a place known as the "Tom Williams bridge." One died in transit. This was, I think, in July, 1870. The distance from the place in Mulky Meadow where the tish were obtained to the Tom Williams bridge is about 'Ai to 4 miles. There was no possible way for fish from Volcano Creek to get into the waters of Mulky Meadow at that time. I have heard lately that fish from Volcano Creek had lieen put in Cottonwood Creek many years before by a man liy the name of Nelson; if so, they did not live, for I have fished in these mountain streams since 1870. In 1879 Mr. Stevens and I took a nice string of fish from Cottonwood Creek, wliich showed that they did well; they would average about 8 inches long. I am positive no fish were ever put in from Kings Kiver, as has been claimed by some. In 1890 (1891) Mr. E. H. Edwards, JI. Hand, J. K. Moffet, and a man named Cook turned a little stream of the Cot- tonwood Creek and caught perhaps 100 fish and took them about 24 miles u|) to Cottonwood Lakes. When they arrived at the lakes quite a number of the fish were dead. Perhaps -50 lived and apparently liave done well. They grow very large in the lakes; some have been taken that weigh over .5 pounds. They are beauties and very fat, but our fish law does not pools of the Kaweah and Tule rivers. At that time ( twenty-five years ago) car]) were introduced into this country. Tliey were kept in ponds at first, but escaped from time to time into the streams, and are now very nU. S.

They liiivc never lieen a iMipuUir tish liere. When canfjiht they are usually thmwii out cm the liaiik and not carried home, anil are seldom eaten by any hut Japanese and Indians. The tirst planting done in the mountains was by a few persons carrying rainbow trout from the Big and Little Kern and their tributaries in cans to the streams and lakes on the western slope of the mountains. Later, clubs were organized and a.ssisteil in the work, and in recent years the State fish commissioners have sujiplied many thousand of small fish for planting in the barren or not well- stocked streams. Among these clubs have been the Visalia Sportsman's t'lub, the Visalia (jame Club, the Esliom Valley Fish and Rifle Club, a clul) at I'orterville, and latterly the Tulare County Fish and (ianie League, and the Fish and (iame Protective Association, of which there are branches at Visalia, !'(vrterville, Threerivers, and near Kings River. The first planting in the mountains of which we have any record was done by Mark Lavelle and Nick Wren in Mineral King Creek, the trout being brought from the Little Kern in caiis on pack ani- mals. Wiley Watson, Arthur Crowley, and W. A. Ward w-ere also among the first to carry rainbow trout from "over the djviile" to the Mineral King region. They were planted in Mineral King Creek, Redwood Canyon Creek, and in Eagle, Monarch, Crystal, and Lady Franklin lakes. Cajitains Parker and Liickett and Lieutenant Dean of the Fourth U. S. Cavalry, and other officers detailed by the acting superintendent of the Secjuoia and (ieneral (irant national parks, during several years lent valualile assistance in the work of stocking the mountain streams, detailing men and pack trains for the purpose.

The melting of the snow furnishes tiie streams with their water supply. Even during the summer the supply of snow is not entirely exhausted, and where such is the case the springs whose reservoirs were filled from the melting- snow furnish the streams with a constant supply of cold water, the temperature of which the short period of warmth through the middle of the day does not markedly artect. Even in midsummer at these altitudes the nights are cold, the temperature often falling several degrees below the freezing point of water. During the day the sky is more freijuently overcast than is the case in most parts of C'alifornia, and in the highest altitudes light falls of snow are not uncommon. Although these latter usually quickly disajjpear they add their contribution of cold water to the streams. These conditions insure a comparatively low temperature for the waters of the tributaries of the upper Kern for the whole year. The tributaries of the Kern, however, all make great and rapid descent to the Kern River. This river also continues to drop rapidly through mountain and foot- hill regions until it reaches the plains. Through a comparatively short distance waters from melting snows on tiie summit of Mount Whitney pass by Whitney Creek and the Kern River, in summer from the temperature of melting snow to the plains below where the temperature reaches a point exceeded by few places in the United States. In these lower regions the waters of the river are not reinforced by rains or springs and sire unprotected by shade of vegetation. Indeed in this region in summer the waters of the Kern are finally lost b}^ absorption and by evaporation after breaking up into numerous winding streams. In recent times the distribution of these waters is nuich modified by the great irrigation .systems that are developing along the Kern. The natural features thus noted bring about conditions of tempera- ture which make the upper Kern with its tributaries lying in the mountains ideal for trout, while during a great part of the year they render the lower portions of the river lying among the lower foothills and in the plains impossible for this fish. The land animals and plants along the l)aiiks of these streams have l)een studied by the members of the Biological Survey. The changes in fauna and flora from the summit of Mount Whitney to the plains about Hakersfield include the extremes to b(> found in the Ignited States. In its descent from Mount Whitney the water passes successively the zones that have been designated Boreal, Transition, Upper Sonoran, and Lower Sonoran ))y the Biological Survey. No like study of the water forms of animal and plant life of the streams of this region has ))een made, but from the nature of the conditions no such well-marked zones could be looked for among the aquatic forms as have been found for the terrestrial species. Nevertheless, a careful study throughout could not fail to bring out interesting facts of the distribution of the forms belonging to the streams. As it is, we do not at the present know accurately the lower lange of the trout, the farthest upper range of the fishes peculiar to the lower portions of the stream, nor the range of any of the other animals that live with them. 40 BULLETIN OF THE BTtAEAU OF FISHERIES. In the following' tal)le are given the temperatures of the Kern River in and about Kern Lake, which is but a widened portion of the river caused by a partial <-hoking of the stream in the recent past. The temperatures were taken in the latter part of July. As can l)e seen, they range from 5:^.5 to 61"^ F. Naturally the morning temperatures are lower than those of the later parts of the da3', as also are those of the lower depths of the water. The records of the maximum and minimum tempera- tures at our camp near the shore line of tiie lake show that tiie air temperature during tlie night was even a little lower than the lowest temperature of the water, while during the day it rose far above it, l)eing, indeed, a high sumnu>r heat. Table 1. — \]'k taken from points extending from one-half mile a1)ove the mouth of the creek to the portion which lies THE OOLDEN TRvOtTT. 41 vcMV noar the South Fork. of the Kern at the old "tunnel."' This latter point i.s about half the distance from the mouth to the .source. No doubt above this point, toward its sources, lower tempci'atures would have been reached. • Although the stream lies in high altitudes, considerable stretches of it wind through meadows where the warmth of the sun has opportunity to raise its temperature. This, how- ever, is compensated 1)V the cold of the niohts and the fi'equent supply of cold water from springs. Table III. — ]'olr(i)i.o Vrevk trmpertitiires. Date. Hour. Temper- ature. Locality.

Rock Creek is a considerable stream, flowing into the Kern from the east, its middle branch or main stream rising- from Sheep Mountain, Cirtjue Peak, and Mount Le Conte. We have but a single record of temperature from it. This is at a point where the trail crosse.s it, and is about one-third the length of the stream above its mouth. The temperature here at 3.15 p. m., July 2^, was 54'-. This ob.servation would indicate that its water.s are about the temperature of those of Volcano C-reek. Siberian Outpost is on the upper portion of a branch, the most .southern of Rock Creek. It i.s near the base of Cirque Peak. A short distance from our camj) small patches of snow still were to be seen. Temperature of air at in p. m., July 24. 52.5' : at 5.45 a. ,m., July 25. 44.25'=. The records of temperature of Whitnej' Creek were made at Crabtree Meadow or in its vicinity. This meadow i.s at a point about one-fourth of the whole length of the stream from its mouth. The record shows the temperature of Whitney Creek to be noticeablj' lower than that of Volcano Creek. This is due to its higher elevation, its sources in Mount Whitney being longer covered with snow, and the fact that even in summer when they are expo.sed they more frequently receive sup- plies from the ligiit snowstorms. 42 BULLETIN OF THE BUREAU OF FISHERIES.

The trout investigations that were made in the vicinity of Mount Whitney, California, during July, 1904, included a brief study of the food of some of the trout found in the waters of that region. This study consisted of a careful examination of the stomach contents of 8.5 trout, these S.5 tish belonging to five difl'erent species which were obtained from si.x diH'erent stivams and one lake. They were caught \\ ith hook and line and were taken at diti'ercnt times of the day, chieHy early in the 44 BULLETIN OF THE BUREAU OF FISHERIES. forenoon uiid toward evening. Tlui.s the contents of these stomachs ought to repre- sent fairly well the natural food of the trout at this season of the year. About 40 of the stomachs were examined at the time the trout were caught, while the remainder were preserved and their contents have been examined since the time of the expedition. Most of the specimens whose stomachs were exam- ined at the time of their capture were measured and a record of the length was made along with the record of contents of the stomach. In some cases also tlie sex of .thi> individual was noted. It was not found practicable to keep a record of the length and sex of all the specimens from which stomachs were taken and preserved, but the stomachs of specimens obtained from different localities were kept separate and a record made of the longest and shortest specimens from which thej- were taken. The relative quantitj- of food in each stomach was estimated — that is, whether the amount of food found was a (juarter, or a half, etc., of the quantity the stomach would hold with ordinary distension. The relative amount of the various food ele- ments was then estimated and recorded in percentages. The percentage method was used rather than the counting method because the contents of many stomachs con- sisted largely of fragments so small that it was impossible to place them in the proper group or groups of insects. However, the number of individuals making up the various percentages was also recorded in cases where it could readily be determined. Onl}' a very general classification of the stomach contents was attempted and the fol- lowing record will show how the various items were noted: Specimen No. 7, length 7 inches; stomach about two-thirds full; contents — 1.5 per cent remains of 7 stone- fl}' nymphs, 95 per cent Chironomida; (761 chironomid larvte and 1 pupa), 2 per cent 1 large fly, 0.5 per cent elytron of a small beetle, 1 per cent ants. The insect frag- ments that were too small to be identified accurately were recorded under the head of "insect fragments" and the Chironomida^ were noted separately from the other Diptera because, in general, the}' were found to be a more important food element than the other Diptera. The other groups are self-explanatory. The following is a summarized record of the results: Salmo whitei p^vermann. South Fork of the Kaweah River. — The stomachs of 12 specimens obtained from this stream at South Fork Meadows, on July 15, 1904, were studied. The specimens varied in length from 5.5 to 8 inches. All the stomachs except 1 were estimated to be half full or more. AracJinida. — Two per cent of the contents of 1 stomach consisted of spiders. Ephemerida. — Three stomachs contained May-fly nynij^hs. two 5 per cent, and the other 3 per cent. Plectera. — Four stomachs contained 90, 25, 15, and 5 per cent caddis-fly larvffi, and 8 contained 90, 20, and 1 per cent cases of caddis-fl}' larvic. Diptera.— 1hve& specimens had eaten 10, 6, and 2 per cent Diptei'a.

Ihi))U))optcra. — Throe stomachs contained ants, two 25 per cent, and the other 1 per cent. IiiKt'ci t'rnriifs. — Small fragments of insects constituted from It per cent to .S5 per cent of tiie entire stomach contents of 9 specimens. Vtyi'tahlc niuttcr. — Five stomachs contained -10, 30, 10, 7, and 0.5 per cent vegetable matter. In one or two instances part of this vegetable matter was prob- ably derived from the cases of caddis-fly larvse. The following percentages show the relative importance of the various elements of the stomach contents for all 12 specimens. These average percentages were obtained b}^ adding togethei' all the percentages of each element and dividing this sum by I'i. Arachnida 0.16, Ephemerida (Maj'-fly larvffi) 1, Plecoptera (adult stone- Hies and nymphs) :3.y, Hemiptera O.OS, trichopter larva; 11.23, cases of trichopter larva; 9.2, Diptera 1.5, chironomid larviv and pupa^ 15, Coleoptera 15, Hymenoptera (ants) 4.23, insect fragments 31. i, vegetable matter 7.3. This shows that trichopter larviv, chironomid larva- and pupse, and Coleoptera were the most important food elements, as these three together constituted a little over 41 per cent of the stomach contents of the 12 trout. Soda Crekk. — Six trout of the same species were obtained from this stream at Quinns Horse Camp on July 10, 190'!. They varied in length from 4.5 to 6.5 inches. Five of the stomachs were estimated to Ije from one-half to two-thirds full and the sixth about one-fourth full. Epheiiwrida. — One stomach contained 15 per cent May-tiy nymphs. Plecoptera. — One specimen had eaten 15 per cent adult stone-Hies and two had each eaten 20 per cent stone-Hy nymphs. Orthjptera. — One specimen contained 25 per cent remains of a grasshopper (locust). Trk'h(i])terit. — Three stomachs contained 60, 20, and 15 per cent caddis-fly larvie and another 90 per cent larva; and larval cases together. ('lih'unoiiiklse. — The contents of one stomach consisted of 1 per cent chironomid lai'vse. Coleoptera. — Twenty per cent of the contents of one stomach and 5 per cent of another consisted of remains of beetles. Ifyiuenoptera. — One stomach contained 15 and another 10 per cent ants. IiiKeci fraymentK. — The contents of all six stomachs consisted of 10 per cent to 99 per cent small fragments of insects. Veijetahle matter. — Two specimens had partaken of vegetable matter to the extent of 5 and 2 per cent. The following are the average percentages for these six specimens: Ephemeridu (May-fly tiymphs) 2.5, Plecoptera (adult stone-flies and nymphs) 9.22, Orthoptera 4.16, trichopter larvw 30.82, chironomid larva- 0.16, Coleoptera 4.16, Hymenoptera (ants) 4.16, insect fragments 43.66, vegetable matter 1.16.

S2 per cent, formed tlll^ most iinportiiiit element of tlic food of these specimens, and adult stone-flies and nymphs were second in importance. LiTTi,E Kekn Rivkr. — The 41 trout (Sii/i/ii) irhlte!) obtained from this stream were caujjiit in the vicinity of a place called Hroder's cabin on July 17, 1904. 'I'iiev varied in lenjjth from 5 to S inches. The stomachs of 34 were estimated to )»' lialf full or more; the others were less than half full.

(h'thujdt'iit. — Two stomachs contained 5(» and 2 percent remains of j;rasshoppers (locusts), and fragments which apj)eared to l)e parts of a mantis composed 2 percent of the contents of another. Ilemi/iteru. — Thirteen stomachs contained from 1 per cent to Id i)er cent I[rliu2)tt'r. Ants I'anked next in importance. Only two of these stomachs contained threadworms (Nematoda). DISCUSSION OF RESULTS. If the foregoing results may bo taken as representative of the various streams from which these specimens were obtained, the trout in them wei-e dependent almost wholly on insect life for their food at the time these investigations were made. In fact, judging from the scarcity of other animal forms that might serve as food, adult insects and the aquatic larvte of insects must play a very important role in the food supply of these trout during the entire year. It is possible, of course, that the small trout may be eaten by the larger ones at times, but no such canni))alistic tendencies wei'e found among the .specimens examined, the only indication of canni- balism noted being the single trout egg eaten by one specimen. The relative importance of the different groups of insects was very different in the different localities. The specimens from the South Fork of the Kaweali River THK OOLDKN TKoUT. 49 had led most iilnuidiintly on trichopter larva', chiroiioiiiid larva' and piq)*, and Colcoptora; trichopter larva? ranked highest with the trout from Soda Creek, with adult stone-Hies and i^ymphs second in importance; those from the Little Kern River had partaken most freely of Coleoptera (beetles) and Hj-menoptera (ants); and the golden trout had fed most freely on May-fly nymphs, adult stone-Hies and nymphs, and adult and larval Trichoptei'a. 'I'hese investigations were ni)t sufficient to deter- mine whether these diti'crences in diet were due to a choice of food hy the trout or whether they were the result of ditl'erenoes in the distribution of the diiierent kinds of insects resulting from local condition,^. The latter was probably a very important factor in producing these differences, as it was noted that the acjuafic larva' varied, not only in actual numbers but also in I'elative abundance, in the difi'erent localities. Vegetable matter formed a comparatively small part of the stomach contents of the specimens obtained from streams, and probably much of this was taken by accident. Three of the trout from Upper Kern Lake, however, contained consider- able quantities of vegetable matter, so that part of it, at least, nnist have been taken ptu'posely. Li the cases where the sex was noted there was no apparent didercnce in the diet of the male and female. ('LAI)O('EKA AND CJOPErODA OF TIIK KEKN ItlA'ER I!F<;(;i<)N.
