FISH-CULTURAL INVESTIGATIONS IN MONTANA AND WYOMING. 
31 
In 1S89 the Irrigation Survey measured the Yellowstone River at Horr and Spring- 
dale, just north of the Park, and obtained results remarkably close to those obtained 
by Mr. Hague. Capt. Dutton says : 
The Yellowstone in August carried at Horr 1,553 second-feet on the 26th of August, and at Spring- 
dale 2,111 second-feet, which is about as low as it may he expected to fall in any season.* 
We examined the Yellowstone River pretty carefully between the lake and the 
falls, for the purpose of determining if any of the whitefish planted there in 1889 by 
Mr. Lucas could be found. Rot one was seen, and it is not believed any have survived. 
Careful inquiry among members of Mr. Wyatt’s road camp failed to elicit any evidence 
of the presence of whitefish. This party had been encamped upon the bank of the 
river for some time and had had excellent opportunities for observing the whitefish, if 
any were there. Trout, both large and small, were very abundant in the river here. 
They are eaten quite freely and are not regarded as being seriously affected by the 
parasitic worm. Many of the trout taken here are said not to be affected at all. 
Blacktail Deer Greek was examined at the crossing of the Cooke City road, and 
Lava Creek or East Fork of Gardiner River was examined between the two falls, 
where one small trout was taken with the hook. Whether this was one of the plant 
made here by Mr. Lucas in 1889 can not be certainly known, as it is reasonably certain 
that trout were found naturally in this creek, as explained by Dr. Jordan in his 
report. 
Red Bock River. — This river was examined by Mr. Clapham 3 miles north of Red Rock 
Station on the Union Pacific Railroad. It rises in Red Rock Lake, about 40 miles 
distant, in the mountains on the Idaho line. Rear Red Rock it is a good-sized stream, 
about 30 feet wide and 20 inches deep. It is full of deep holes and eddies. The bottom 
is usually quite rocky, but there are stretches of sand and mud. The water is clear, 
but not very cold, the temperature being 58°. This is a very good fish stream, blobs, 
dace, suckers, grayling, and whitefish being abundant, and one specimen of the ling 
(Lota lota maculosa) was taken. Ro trout were found here, though higher up the 
stream and in Red Rock Lake trout are said to be abundant. The ling is also said to 
be common in Red Rock Lake. 
Beaverhead River. — This is simply a continuation of Red Rock River, the name 
changing at Grayling Station. We examined this river at a point 2 miles above Dillon, 
Montana, and from there downstream to below the town. It is there a rather large 
stream, 50 feet wide and at least 2 feet in average depth. It flows through Dillon 
Yalley, which is several miles broad. It has mud or adobe banks, usually covered 
with a rank growth of willows and other bushes. The bottom is usually one of gravel, 
but there are muddy places here and there where the current is less swift and where 
the stream is filled with Ranunculus and many species of Algae. Along its banks are 
many ponds filled with water vegetation. The temperature of the water at noon, July 
27, was 63°. This is apparently too warm for trout, as none were seen, and we were 
told that none are found this far down the stream. It is, however, an excellent stream 
for whitefish and grayling, with which species it is well supplied. Suckers, dace, and 
blobs were also abundant, the blobs being exceptionally large. Black bass would 
certainly do well in such a stream as this.
