4A-(1)» Logy Creek. — (May 1 to 4, 19o7s Hanavan and Lobell.) 

 This tributary enters Satus Creek 24 miles upstream and is 27 miles 

 long. The lower 2.2 miles were surveyed, and the next 11 miles in- 

 spected. The observed flow vras 18 to 20 c.f.Sej but the creek is 

 reported to be dry occasionally near its mouth during the late 

 summer months. Otherwise there would be some suitable spawning 

 area in the lower 3 l/2 miles. The remainder of the stream is 

 fairly steep, and an impassable falls 15 feet high was found 14 

 miles upstream. 



4B. Toppenish Creek. — (Inspected April 29, 1937 i Hanavan k Lobell.) 

 This stream is approximately 60 miles long, entering the Yakima 68 miles 

 upstream just below Granger, Washington. In the lower 25 miles, up to 

 the confluence of Simcoe Creek, it flows through a flat swampy section 

 where it serves as a drainage canal. In the next 10 mileSj up to a 

 dam 4 feet high the stream is diverted into many small channels for 

 irrigation purposes. These channels have considerable good spawning 

 area, but one or another of them are reported to be dry at intervals 

 during the summer. The dam has a crest of 40 feet, and when inspected 

 had a 6 inch flow of water over it, but diH-ing the summer irrigation 

 period the entire flow is reported to be diverted into a large ditch 

 at the dam. The remaining 25 miles of stream above the dam maintains 

 a flow of water throughout the year, and has good spawning areas. A 

 small run of steelhead is reported to enter the stream, and to pass 

 over the dam during the period of high -vmter. The stream is of little 

 present value to salmon. Rainbow trout ere reported to be numerous. 

 The stream is entirely within the Indian Reservation, and Indians 

 customarily take fish at the dam. 



4C« Ahtantmi Creek »-«- (October 20 and November 8-13, 1935 1 

 ■Vfhiteleather and Shianan.) This creek Joins the Yakima 94 miles 

 upstream near Union Gap, Washington, and was surveyed for a distance 

 of 21 1/2 miles to the confluence of the North and South Forks. The 

 stream is bordered by the Yakima Indian Reservation on the south 

 bank, and hence is subject to Indian fishinge The gradient is slight 

 to moderate. The gradient in the lower 8 l/Z miles is slight, the 

 bottom having a large amount of mud and sand with only occasional 

 spawning riffles. There is a concrete dam 3 l/2 feet high 17 miles 

 upstream that diverts water into an artificial side channel called 

 Hat ton Creek , and l/4 mile farther upstream a second and similar 

 dam diverts into another channel called Bachelor Creek. Water is 

 shifted back and forth between these three channels, any of which 

 may be dry or nearly so during the summer and fall months. 



The main stream channel has 2 3 irrigation diversions, many of 

 which have low earth, rock, or board dams, but no fishways, and are 

 barriers at low water stages. The only diversion that is screened 

 is the Indian Service Diversion Canal 18 l/2 miles upstream, which 

 has a maximim capacity of 70 c.f.s., but is allovied to take only 

 one-fourth the stream flow when the latter drops below 100 c.f.s. 

 diB canal was screened by the Bureau of Fisheries (predecessor 

 of the Fish and Wildlife Service) in 1929.
