Only two of the several tributaries were found to be of possible 

 valjie to salmon, the others being either too small or too steep and 

 rough. 



12G-(1). Chickamin Creek *— (July 14, 1937; Jobes.) Enters 

 the Chiwawa River 12 miles above the mouth. It is 8 miles long, 

 of which the lov/er 2 miles were surveyed. The creek vras 20 feet 

 wide and had a flow of 61 c.f .s. The lovfer mile on the Chiwawa 

 valley bottom has a moderate gradient and good spavming riffles 

 between adecfuate resting pools. The gradient increases rapidly 

 above; most of the stream course being in a steep canyon, and 

 bordered by dense brush, with spawning area confined to small 

 patches. The discharge becomes low in the fall, but the lower 

 section is usually passable to fish. Three log jams in the 

 lower 3 miles may be barriers at low water. Chickamin Creek 

 could support a small run near its mouth, but no migratory 

 fish have been known to enter it in recent years. 



12G-(l)a. Marble Creek . — Entering Chickar,iin Creek about 

 1 mile above the mouth, is steep and has only a small amount of 

 spawning area near its mouth. It was 8 feet wide and had a flow 

 of 15 c.f.s. 



12G-(2). Rock Creek . — (July 14, 1937; Baltzo.) Enters the 

 Chiwawa River about 17 miles above the mouth. The stream is 12 

 miles long, of which the lovjer 5 miles were surveyed. The discharge 

 was 64 c.f.s., somewhat greater than the normal flow. The lov/er 

 mile, in the flat Chiwawa Valley, has a moderate gradient and con- 

 tains all of the good spawning area in the stream, amounting to an 

 estimated 14,000 square yards., Above this section the stream is in 

 a steep, narrow, forested valley and has an average gradient of 

 more than 200 feet per mile. It is almost a continuous succession 

 of clear, cold, tumbling cascades* Salmon could not ascend very 

 far above the lovrer mile, and no runs were reported. Trout have 

 been planted, and the lov/er part of the stream is heavily fished. 



12H. Fish Lake Stream and Fish Lake. — Fish Lake Stream enters 

 the Wena tehee River 2 miles dovmstream from Lake Wena tehee. It extends 

 for 1 mile to Fish Lake. The gradient is slight to moderate, and the 

 flow is normally 5-10 c.f.s., although the stream may become dry in 

 late summer. Numerous beaver dams prevent the migration of fish up 

 or down the outlet stream. 



Fish Lake is approximately 1 l/2 miles long and 1 mile wide. 

 The greatest depth is about 50 feet, but there are large marginal 

 areas of shallow water. The bottom is composed mainly of mud, 

 VTith one or two small gravel banks. The lake is fed by several 

 large springs with short inlets, and by melting snows from the 

 adjacent mountain slopes. The fish population includes perch, 

 largemouth bass, several cottoids, squawfish, and a few kamloops 

 trout. Neither the stream nor the lake is of value to anadromous 

 fish.
