with a very limited amount of spawning area occurring between 

 cascades o About 75 percent of the stream bed in this section 

 consists of large rubble and boulders. Above this point the 

 stream flows through a rocky gorge where the gradient is very 

 steep,, and there is no suitable spa-vpiing area. At the lower 

 end of this gorge there is an impassable falls 25 feet high. 

 The discharge near the mouth was estimated to be 10 Cof.s. The 

 flow is fairly constant throughout the year, except for sudden 

 spring freshets J which raise the water level several feet and 

 flood the lower valley <> The streeim is of little potenitalmlue 

 as a salmon producero 



16C='(4)o Lake Creek o— (August 28-29, 1935, Whiteleather, 

 Shuman, and Burrows ») Jjeike Creek enters the Chewack River 

 approximately 2 3 miles above the mouth o The stream extends 

 for about 6 miles to Black Lake* This lake is about 1 mile 

 long and slightly less than l/4 mile wide. The stream extends 

 for about 8 miles above the upper end of Black Lake, and here 

 is often called Upper Lake Creeko The stream was surveyed from 

 its confluence with the Chewack to a point about 1 l/2 miles 

 upstream from the lake, where it is blocked by a combination of 

 a rock slide and log jam 4 feet high and 40 feet long forming a 

 total barrier to migratory fish. Lake Creek was 24 feet wide nftar the 

 mouth, and was discharging about 16 c.f .s. The vreiter temperature 

 was 52°?. at the mouth, 62^, at the surface of the lake, and 45°F, 

 in the stream just above the upper end of the lake. The gradient 

 is fairly steep in the lower section, and was estimated to be about 

 80 feet per mile from the mouth to the lake. There are numerous 

 cascades, some of which might be difficult for the passage of salmon© 

 There is some possible spawning area in scattered patches between small 

 pools and cas cades o A storage dam 2 feet high at the outlet of the lake 

 would be a barrier to migratory fish at low water stages. 



The gradient in the surveyed section of Upper Lake Creek was esti- 

 mated to be 25-30 feet per mile. This short section up to the impassable 

 log and rock jam seemed to offer some good spawning area for salmono 



No salmon or steelheads were found anywhere in the stream, and it 

 was reported that r\ms of these species never has been known to entero 

 The stream appears to be of no great potential importance to salmon. 



16D. Wolf Creek o — (May 1937j Jobes and Baltzo.) Wolf Creek 

 enters the Methow River 2 l/2 miles above Wlnthrop, or approximately 

 50 1/2 miles above the mouth. It is a good size stream, about 13 miles 

 long. In the lower part of its course it flows through the cultivated 

 Methow Valley o Most of the flow is diverted through a flume into 

 Patterson Lake. The normal water level of this lake has been raised 

 32 feet by a dam at the outlet in order to increase the storage capacityo 

 Only enough water is allov/ed to pass the Patterson Lake diversion to 

 comply with the irrigation rights of farms along the stream below that 

 point. As a result the stream is entirely dry at its confluence with
