The Ha tton or Hollow Creek Channol is 10 miles lonp, and returns 

 to main Ahtanum Creek 7 1/2 miles above the mouth of the latter. It 

 has 33 unscreened diversions and several low dams, one of which is 

 located only 200 yards above the return to Ahtanum Greek and is a 

 definite barrier to fisho Due to this barrier and to the fact that 

 the regulated flow is so intermittent^ none of the spewning area in 

 this channel is of value. 



The Bachelor Creek Channel is over 17 miles long and returns at 

 a point 2 o6 -miles above the mouth of Ahtanum Creek, It has 38 un- 

 screened diversions and several low diversion dams, one of which,, 

 located 2 miles upstream, is a low water barrier. The water fluctu- 

 ation in this channel also makes it unusable to salmon.. 



Ahtanum Creek formerly had good runs of salmon and steelhead. 



The only fish still reported to enter the stream are s. few chinook 



in the lower 2.6 miles belov/ the Baohelor Creek channel during high 

 water periods. 



4C-(l)o North Fork of Ahtanum Creek . °° (November 13 and 14, 1935 

 and September 30, 1936 i Shuman and Whiteleather. ) This stream is 20 

 miles longj the lov^er 13.2 miles having been surveyed. It is inaccessi = 

 ble and therefore of no value to anadromous fish. The flow from late 

 July to the following winter is usually from 12 to 45 c.f.s. and during 

 the spring runoff is usually from 125 to 275 c.f.s. The stream is 

 sluggish in the lower 3 miles and flows in several channels on which 

 there are occasional beaver dams. The remainder of the stream has 

 many good riffles with suitable spawning area. There are 5 unscreened 

 diversions, and a diversion dam 4 feet high 1 l/2 miles upstream is a 

 low water barrier. Rainbow and cutthroat trout were reported. 



4C-(2)o South Fork of Ahtanum Creek .— (November 14, 1935s 

 Shuman and Whiteleather. ) This stream is 13 miles long, 5.3 miles 

 having been surveyed. It is inaccessible to anadromous fish. The 

 usual flow is from 5 to 20 Ccf.s« with about 90 c.f.s » during the 

 spring runoff. The gredient is fairsly uniform and there were many 

 small riffles. There are 6 unscreened diversions, 2 being above 

 small brush dams that are probably not barriers. Prior to 1900, 

 salmon ascended at least the lower 2 miles of this stream, but none 

 have been reported sincse then. 



4D. Naches River . ^° (July 16-2 3, 1935, and July-August, 1936; 

 Hanavan, Whiteleather, and Burrows,) The Naches is the largest tribu- 

 tary of the Yakima River extending approximately 51 miles to the conflu- 

 ence of the North and South Forks, It joins the Yakima River 101 miles 

 above the mouth at a point just above the City of Yakima, Washing ton » 

 It was all survyed. The gradient is moderate, the river having cut 

 a deep valley from its headwaters on the slopes of Mto Rainiero The 

 stream flow now fluctuates less than formerly, es it is partially reg- 

 ulated by the Tieton and Bimping Lake reservoirs. The spring runoff, 

 fed by melting snows on Jft. Rainier and the adjacent Cascade slopes, occurs 

 between late March and mid June, the flow usually being between 1,000
