There is approximately one mile of stream above the dam that is of 

 value to migratory fish before the stream becomes too steep. Logging 

 operations are nearljr completed in the upper watershed, and several log 

 jams Trere found, all of which were believed to be passable. 



There is sufficient suitable spawning area below the dam for at 

 least 2,000 pairs of salmon or steelhead trout, with the best spawning 

 area located in the first 3 miles above tidewater. The 1946 survey 

 party found a rock crusher removing gravel from the stream bed at a 

 point ij miles above tidewater. There is spawning area above the dam 

 sufficient for an additional 1,000 pairs of salmon or steelhead trout, 

 provided that sufficient flow is maintained to permit fish to reach and 

 ascend the fish ladder at all times. 



Local residents report fair runs of silver and chum salmon and 

 steelhead trout. Ten adult steelhead trout and 98 redds vfere observed 

 by the 1946 survey party. Seven of these redds were located above the 

 dam site. Carp were found in the lower slough section. 



The only tributary of any possible importance enters in the canyon 

 section and had a flow of 10 c.f .s. Since its stream bed is composed 

 chiefly of bedrock and large rubble it is considered of little value to 

 salmono 



3. Youngs River . — (May 2-3, 1946 j Parkhurst, Zimmer, Brewington, 

 and Maltzeff), Youngs River enters Youngs Bay aliout 10 miles above the 

 mouth of the Columbia River. The stream is about 18 miles long, of 

 which the lower 7 miles is a tidal slough of little value to spawning 

 salmon, but may have considerable value as a rearing area for young salmon. 

 The stream was surveyed for a distance of 3/4 mile from tidewater to the 

 impassable Youngs River F&lls, and was inspected at various points above 

 the falls. The stream was 30-60 feet wide below the falls and had a flow 

 of 107 c.foS. The maximum discharge was 6,300 c.f.s.on November 24, 1927, 

 and the minimum discharge Tiras 3*7 c.f.s. on September 22-23, 1938 (U. So 

 Geological Survey Records). There is usually a discharge of 10-20 Cof»s. 

 during the fall salmon spawning season. The water temperature was 56-58°F. 



The only available salmon spawning area is located in the short sec- 

 tion from tidewater up to the falls. Uere there is a succession of ex- 

 cellent spaiTning riffles capable of supporting approximately 500 pairs of 

 salmon. This area is utilized by fall runs of chinook, silver, and chum 

 salmon and steelhead trout. There are also spring spawning runs of sea 

 lampreys, suckers, and squawfish. Bass, catfish, crappie and other warm- 

 water fish inhabit the lower slough area of the river. 



Youngs River Falls is approximately 40 feet in height and drops 

 abruptly over a rock ledge into a deep pool below. The section above 

 the falls has a moderate gradient for several miles and extends through 

 a rugged, logged-off hilly area. Tliere is a large amount of spa•^^ming
