areas and some would interfere with fish passap;eo The two forks 

 are reported to maintain a f^ood flow of cool water, and are supplied 

 by two small mountain lakes » Trout fishing s very g;ood in the upper 

 Manastash and its tributaries « There is spawning area for a large 

 number of salmon and steelhead-in this creek and its upper brancheSj, 

 all of which is now inaccessible due to irrigation facilities on the 

 lower courses o . 



4Jo Taneum greek o— - (July 20, 1936? Shuman and Koliosn.) 

 Enters the Yakima approximately 148 miles above the mouth. The 

 main stem extends for 12 miles to the confluence of the north and 

 south forks, and was conpletely surveyed. The lower 4 miles of 

 the course is through cultivated valley lands and the remainder is 

 in a steep, rocky canyono There are some good spawning areas but 

 these are now mostly inaccessible and of little value to anadromous 

 fish because of irrigation demands and numerous low damso Before 

 the completion of the Taneum Canal in 1910 the stream supported a 

 good run of silver salmom, but no runs have occurred for many years. 

 Diversions and obstructions are as f ollov/s s 



An irrigation ditch takes off from a brush wing dam on the south 

 bank 1 l/2 miles upstream. It was diverting only 2 c.f .So when in- 

 spected, but has a much greater capacity, and is unscreened. 



A concrete dam 2 miles upstream has a spillway 3 feet high, with 

 provision for the use of 2 foot flashboards. It diverts all water 

 from the stream at times. 



The Taneum Ditch takes off at the south end of the dam, and was 

 diverting 85 c.foS. at the time of bbservation. 



The Lorn Thompson Ditch takes off from the north bank 2 l/2 miles 

 upstream o It was unscreened, but was not in operation at the time 

 of observation. 



A small fl\ame takes off 5.2 miles upstream. It is unscreened 

 and is located above a log dam 1 1/2 feet high. 



A ditch 3 feet wide takes off on the north bank approximately 

 6 1/2 miles upstream, above a log dam 1 foot high. It is imscreened. 



4J-(1)» North Fork of Tfaneam Creek .— (August 3, 1936 5 YJhi teleather 

 and Jobes.) This stream is 11.3 miles long, the lower 5 miles having 

 been surveyed. It flows in a narrow wooded mountain valley, has a 

 moderate gradient and good spawning areas in the section surveyed. 

 Farther upstream the gradient is steeper and there is a greater amount 

 of large rubble in the stream bed. There are no obstructions or diversions 

 except a log jam 3 l/2 miles upstream that may be a barrier at low water. 

 The stream has native trout, but salmon and steelhead runs never have been 

 reported. The observed flow was 8 o.f.s.
