12A-(l)o Sand Creek o<-° (June 28, 1935; Suoniela and Shuman.) 

 This tributary of upper Mission Creek extends through a narrow, 

 forested valley for a distance of 8 miles, of which the lower 3 

 miles were surveyed. The stream bed contains a large amount of 

 sand which greatly reduces the amount of suitable spawning area. 

 A log jam 1/4 mile above the mouth and a falls 2 1/4 miles upstream 

 were both barriers to fish at low water. The stream appears to be 

 accessible and' of value only to a few spring run steelhead trout. 



12A-(2)o East Fork of Mission Creek .— (jxine 28-29, 1935, 

 Suomela and Shuman.) Extends for 6 l/2 miles, of which the lower 

 2 1/2 miles v/ere surveyed. The numerous beaver dams forming low 

 water barriers as well as the large percent of mud and sand in 

 the stream bed limit the available spawning area. The stream is 

 of no present value to salmon. A small run of steelhead trout is 

 able to ascend during the spring freshets. 



12B. Peshastin Creek . — (October 13-14, 1935; Burrows, 

 ?fhiteleathex% and Shuman.) Enters the Wenatchee River about 21 

 miles above the mouth, and approximately 2 miles above Dryden 

 Dam, The stream extends for 18 miles, of which the lower 15 miles 

 were surveyed. The watershed covers a rugged forested, moiintainous 

 area, and the stream gradient is fairly steep, with numerous cascades 

 and low falls. However, there are seme small, scattered spawning 

 areas. The value of the stream for fish has been greatly reduced by 

 irrigation use. Three low dams located 2, 2 l/2, and 6 miles upstream 

 are barriers during the irrigation season. There were seven wing dams 

 and nine irrigation diversions in use, of which five since have been 

 screened* Chinook fingerlings were observed in 1944, and in 1945 a 

 few spring chinooks were seen spawning. Fair runs of steelhead trout 

 also were observed in 1944 and 1945. However, in 1946 and 1947 no 

 salmon or steelhead were found. 



12B-(1). Ingalls Creek . — (July 27, 1936; Suomela and Jobes.) 

 Enters Peshastin Creek 8 miles above the mouth. It is 14 miles long, 

 of which 6 1/2 miles were surveyed up to an impassable 40 foot falls. 

 The stream gradient is steep, being over 200 feet per mile, and the 

 stream is mainly a series of cascades in a narrow, steep-sided, rocky 

 canyon. Spawning area is confined to small, scattered patches that 

 might accommodate only a few fish. There is a lov; dam 3/4 mile up- 

 stream with a diversion of 28 c.f.s. to a small eleotric power plant. 

 No salmon are reported, and steelhead are seldom seen, although cut- 

 throat trout and Dolly Varden are taken by fishermen. 



12c. Chums tick Creek .-.- (June 25-26, 1935; Whiteleather and 

 Burrows.) Enters the Wenatchee River 24 miles above the mouth, just 

 below the town of Leavenworth, Washington. The stream is 13 miles 

 long, of which 11 miles were surveyed. The gradient is moderate, and 

 there is a large amount of sand in the stream bed. The only good 

 spawning area occurs in the lov/er 2 miles, v/hich could accommodate 

 several hundred salmon spawners. There were thirteen unscreened
