BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Pataha River . — This stream was examined at Starhuck Arigust 14. Temperature at 4 p. m., 68'^; 
air, 66°. Width, 50 feet; depth, 1 foot; current, 2 feet. The Pataha is of some importance and is 
well supplied with the common iishes of the region. 
Pend d'Oreiile River . — There are two important lakes which are drained hy this river — Flathead 
Lake, in Moiitaim, and Lake Pend d’Oreiile, which is in Idaho, near the Washington State line. 
Examination.s were made at Flathead Lake* in 1891 by Evermaun and .Jenkins, and in 1892 by Gorham 
and Woolman, who found the '‘falls” in Flathead River near the outlet of Flathead Lake to consist 
simply of a series of rapids, which do not interfere in the least with the free movements of fish. From 
this iioint down Flathead River possesses no falls or obstructions of any kind, and there is none in 
Clarke Fork until near Lake Pend d’Oreille.t 
Not far above Lake Pend d'Oreiile, in Clarke Fork proper, and near a station on the Northern 
Pacific called Thompson Falls, are some small rapids which are no more serious than are those in 
Flathead River. This is according to Dr. Gorham and Mr. Woolman. We did not deem it necessary 
to revisit these two places, as Dr. Gorham’s notes and the information which we gained through 
conversations with a number of persons who were familiar with that part of the river convinced us 
that there are no obstructions of any importance above Lake Pend d'Oreiile. 
We examined this river pretty carefully from the outlet of Lake Pend d’Oreiile to near its mouth, 
or where it joins the Columbia just across the British Columbia line. While that portion of the river 
above Lake Pend d'Oreiile is still spoken of as Clarke Fork, the portion below Lake Pend d’Oreiile 
is, ill that region, known only as the Pend d’Oreiile River. From Sand Point, Idaho, which is at the 
outlet of Lake Pend d’Oreiile, to the Washington line is about 25 miles. In this portion of the river 
there is only one fall or rapid, and that is Albany Falls, sometimes known as Villard Falls or 
Seuiaiiuoteen Falls. These falls are about 1-|- miles above the little town of Newport, Idaho. The 
falls are divided by a small, rocky island, upon which is built one of the piers of the railroad bridge 
which is used by the Great Northern in crossing the river at this place. 
The relative position of the bridge and the falls is shown in the above diagram. 
These falls are scarcely more than pretty steep rapids and would not interfere at all wit’u the 
ascent of salmon. The iiart to the loft of the islands (going down stream) is just above the bridge. 
*For information concerning the upper waters of this system see Evermaun, in Bull. U. S. Fish 
Commission for 1891, pp. 1-90. 
tin 1883 Mr. Livingston Stone, under the direction of the U. S. Commissioner of Fish and Fish- 
eries, made an extended exjiloration of Clarke Fork and the Columbia River with reference to the 
selection of a suitable site for a salmon-breeding station. In Mr. Stone’s interesting report (Report 
U. S. Fish Comm, for 1883, 237-255) is given much valuable information regarding the upper portion 
of Clarke Fork and the Big and Little Spokane rivers. He found, what our own inquiries confirm, 
that salmon never reach Lake Pend d’Oreiile, but thought they were jirobably kept back by the falls 
at the mouth of the Pend d’Oreiile.
