BeloTfr the city of Waitsburg the river has an abundant popu- 

 lation of suckers, chubs, and squawfish that would compete seriously 

 with any form of food or game fish. 



The Chinook salmon run in the Touchet had been reduced to 

 only a few fish at the time of the survey in 1935* A fair number of 

 steelhead trout continue to enter the stream. Before the Nine Mile 

 dam was constructed on the main Walla Walla River the Touchet was 

 said to have had excellent rains of chinook salmon and steelhead. 



The Touchet River has the best potential fishery value of 

 any stream in the Walla Walla River system* It has no serious bar- 

 riers to fish migration, and its diversions are mostly small. Suit- 

 able spawning, rearing, and resting areas are niimerous and extensive. 



5d-(1). Wynett Canyon Creek , 5D-(2). Copper Creek , 5D-(3)» 

 Whiskey Creek , 5D-(U). Sorghum Hollow Creek , 5D-(5)» Payne Hollow 

 Creek , and 5D-(6). Patit Creek .-(jTme, 1935; Burrows and White- 

 leather.) These are all small, intermittent streams entering the 

 Touchet River between the mouth and the confluence of the north and 

 south forks. They are of no value to salmon. 



5D-(7). North Fork Touchet River .— (June 15-19, 1935; Suomela 

 and Shuman.) Joins the south fork to form the main Touchet River 

 6l,5 miles above the mouth of the latter. The stream has a total 

 length of about 21 miles, of which the lower 19 miles were surveyed. 

 Above this point it divides into several small branches of no possi- 

 ble value to salmon. The average width at the mouth was about UO 

 feet and near the upper terminus of the survey about 25 feet. The 

 discharge at the time of survey was about UO c.f.s. The stream is 

 practically one continuous riffle broken only by a few large boulders 

 and logs. Suitable spawning areas are excellent and extensive, forming 

 over 68 percent of the stream bed, or about 150,000 square yards. 

 Before the Nine Mile dam was built on the main Walla Walla River this 

 stream supported large runs of chinook salmon and steelhead trout. 

 No chinooks were observed during the survey, but a number of steel- 

 head were seen on the riffles, and a few were caught by anglers. Un- 

 like the main Touchet, this stream apparently has no population of 

 suckers, chubs, or squawfish, as none of these fish were seen or re- 

 ported. Dolly Vard en, rainbow trout, and whitefish, are present in 

 fair noimbers. 



There are eight low dams and thirteen small diversions with- 

 drawing a total of only l8 c.f.s. None of the dams is a total barrier 

 to fish. The city of Dayton water supply dam, 2 feet in height, is 

 the only permanent dam. The diversion is screened. 



5D-(7)a, Wolf Creek. — (Jime 9-10 & 17, 1935; Suomela and 

 Shuman.) Enters the North Fork U miles above the mouth. The stream 

 is about 20 miles long, of -which the lower 16-1 miles were surveyed* 

 It has an average width of about 25 feet, and at the time of survey 

 the discharge was estimated at 30 c.f.s. Suitable spawning area was 

 almost entirely lacking in the section above the terminus of the 

 survey, but in the surveyed section these areas were extensive and
