^^ C^eEl^m River o— (July 25-26, 1941| Weber and Holland.) 

 Joins the Yakima River 169 miles above the mouth. The river is 

 33 miles long^ of which the lower 8 miles up to the impassable 

 CieElum Lake Reservoir Dam were surveyed.. 



The flow below the reservoir dam is under regulations, and is 

 greatly reduced after the end of the irrigation season in mid 

 Ootobero During the winter impoundment period the discharge is 

 St.ldom more than 20 to 30 CofoSo From April to October the discharge 

 is often 600 to 2^000 c«f.5e The stream section below the reservoir 

 is of little value to fish because of the fluctuations in reservoir 

 dischargee A low rubble dam about 1 x/2 miles below the reservoir 

 supplies domestic water for the town of CleElxm, the diversion being 

 protected by a panel screen. 



The 135 foot high reservoir dam was completed by the U. S„ Bureau 

 of Reclamation in 1933 for irrigation purposes. It is improbable that 

 a fishway ever will be built over this dam^ and for this reason the 

 river and its tributariea above the reservoir were not surveyed in 

 detailj, although it is known that the natural lake on the site of 

 the present reservoir and additional lake and stream spawning areas 

 farther upstream formerly supported good runs of blueback a:ii ohinook 

 salmon and steelhead trout. Landlocked bluebacks or kokanee still 

 are present^ together with good populations of rainboWj cutthroat, 

 and Dolly Varden trout. 



4M"(1). Domerie Creeko"= The only 'tributary of the GleElia 

 River' below the reservoir dam. Most of its fiov; is diverted 2 

 miles upstream for the water supply of the toiAm of Roslyn, and the 

 stream is therefore of no value to salmon. 



4M''(2)e Cooper Rivero-" Enters the CieElum River 20 miles 

 above the mouthy, and extends for a distance of 9 miles „ It is 

 ma-jcessible to anadromous fisji because of the impassable CiemElum 

 reservoir dairij, and therefore was not surveyed. 



4R'I-{3)» Waptus River. ==■ Enters the CieElum River 22 miles 

 above the mouth, and extends for a distance of 9 miles to Waptus 

 Lake. It is Inaccessible to anadromous fish because of the impassable 

 CleElura reservoir dam, and therefore was not surveyed. 



4No Big Creek.-" ';^Febraary 19, 1935s Shamano) Enters the 

 Yakima 178 allies upstream, and extends for 10 miles. It is used 

 extensively for irrigation, there being 11 water rights allowing a 

 total diversion of 26,4 o.f .a, Ci: May 3, 1937, its flow was 40 

 Oof o*>o and on July 3, 19375 it was estimated at 10 c.f .s. The 

 lower 2 miles of the stream below the diversions are usually dry 

 d'a:rlng the fcaaaier^ but a few steelhead trout still ascend the creek 

 during the spring high water period.
