Chinook salmon into the Btmiping River, although the greater portion 

 is said to have spawned in the American River, its largest tributary. 

 A few chinooks were observed by the survey party in deep resting 

 pools, hut it was impossible to make an accurate count. Landlocked 

 sockeye salmon (or Kokanee) have been planted in Bumping Lake, and 

 rainbow, cutthroat, and Dolly Varden trout and whitefish were observed 

 in the stream. The river is heavily fished and the present size of 

 fish taken is reported to be much smaller than formerly. 



4D-(4)ao The American River » — (July 28-29, 1935 Whiteleather 

 and Burrows.) Fnters Bumping River 3 l/3 miles above the mouth of 

 the latter, and extends for approximately 21 miles into the Mt. Rainier 

 National Forest. The lovrer 18 miles were surveyed. The flow from March 

 to July is usually 100 to 600 c.f.s., and fran July to December it is 

 25 to 100 c.f.s. December and January flov/s are variable, but usually 

 tyver 100 c.f.s., while the February flow is often below 100 c.f.s. The 

 gradient averages 55 feet per male, although in the lovrer 5 miles it is 

 over 100 feet per mile and contains a preponderance of large rubble. 

 Resting pools average 6 per mile, and are often deep and well protectedo 

 There are no dams or diversions in this stream. The river enters a 

 narrow gorge 14 miles upstream, where it drops 100 feet in 400 yards 

 in a series of cascades. At normal water levels these cascades do not 

 form a complete barrier to fish, but at lo?r water periods there is not 

 sufficient flow over the rocks to perrat fish passage. The entire stream 

 has excellent spawning riffles, with the middle and upper sections being 

 of the highest value. The American River was an excellent c hi no ok salmon 

 producer in the past, but there was only a fair r\xn at the time of the 

 survey, when the fish were observed in the deep resting pools. The stream 

 is heavily fished and produces fair numbers of rainbow, cutthroat, and 

 Dolly Varden trout. 



4D-(4)a-i and ii. Cooper Creek *— 9 miles upstream and Union Creek 

 11 miles upstream, are the chief tributaries of the American Rivero ~ 

 Although only 5 miles long they have well sustained spring flows of 

 35 to 40 c.f.s. Both have steep gradients, but contain some spawning 

 areas near the mouths. Union Creek has a series of falls, 12 to 60 

 feet high, beginning l/2 mile upstream. 



None of the tributaries of the upper Naches (often called the 

 Little Naches above the confluence of Bumping River) have been surveyed, 

 Crovj Creek, 4D-(5), entering 44 miles upstream is the largest, being 

 over 16 miles long. It was inspected on May 5, 1937 when it had a 

 flow of approximately 100 c.f.s., but was too turbid to survey, ouartz 

 Creek , 4D-(6), entering on the opposite bank and flowing 40 c.f.s ,, 

 was also too turbid, 



4E. Moxee Creek.-- Entering the Yakima ^ver near the Wenas 

 Creek confluence was not surveyed, but has a small summer flow and 

 is believed to be of no value for salmon, due to irrigation demands, 



4F, Wenas Creek , — (May 6, 1937; Jobes and Baltzo,) Wenas 

 Creek enters the Yakima 106 miles iipstream is approximately 30 miles 

 long, and had a flow of 25 to 30 c.f.s. The stream is often dry
