16G. Lost RiTero"- (August 15, 31, and September 1, 19355 

 Tffhite leather, Shunian, and Burrovrso) Lost River enters the Methosr 

 River approximately 70 miles above the moutho The stream is about 

 22 miles long, of which the lower 7 miles were surveyad ~ip to an 

 impassable rook slide 20 feet high and extending completely aorosa 

 the river just above the confluence of Monument Creeko There is a 

 high impassable falls near the confluence of Drake Creek approxi- 

 mately 12 miles above the moutho Lost River was about 50 feet wide 

 near the mouthj, and was discharging about 120 CofoSo on August 15, 

 1935. The water temperature ranged from 49°Fo to 51°Fo The 

 gradient is moderate to steep, with numerous cascades a Good 

 spawning areas are most extensive in the lower 4 miles, up to the 

 confluence of Eureka Creeko Above this point the possible spayrning 

 areas are of poorer quality, the greater part of the stream bed 

 being composed of large rubble. 



Lost River was at one time heavily populated with chinook 

 salmono Indians from the surrounding regions foraierly went there 

 to obtain their winter supply of these fishc Local residents consider 

 Lost River to have been next in importance to the Chewack River &3 

 a salmon produoero The unfavorable conditions fonnerly imposei on 

 the lower Methow River, and especially the impassable pov/er dam built 

 at Pateros in 1915, resulted in the virtual extermination of the runs 

 into Lost River o The stream is of great potential value in any 

 fisheries rehabilitation program for the Methow systemo 



16G-(1) Eureka Creek o— (September, 19355 Whiteleather, 

 Shuman, and Burrows o) Eureka Creek enters Lost River approximately 

 4 miles above the' mouth. It is a good size stream, about 14 miles 

 long, and forks about 6 miles above the moutho It was surveyed for 

 a distance of only 3/4 miles, up to an impassable fails 35 feet high« 

 The gradient is steepo It is not an important stream to migratory 

 fisho 



16H» Robinson Cre ek o-° (May 4, 1937$ Jobes and Baltzo.,) 

 Robinson Creek joins the West Fork of the Methow to form the main 

 Methow River approximately 71 l/2 miles above the moutho It i£ 

 about 8 miles long. At the time of obsenration, during the peak 

 of the spring ran=off, the stream was over its banks and discharging 

 more than 200 Cof oSo It maintains a fair flow throuthout the yearo 

 The gradient is steep over most of che coarse, with almost ssontiMuous 

 oasoades falling over predominantly large rabble© Suitable spawning 

 area for salmon and steelheads is very limited, and the stream is of 

 little potential value to migratory fish.
