There is a concrete irrigation diversion dam located about 8 miles 

 above the mouth. This dam is 10 feet high, and is a barrier to fish. 

 The ditch was estimated to be withdrawing more than 30 c,f»s» at the 

 time of the survey. Approximately 100 feet farther upstream there 

 is another low irrigation diversion dam diverting about 5 c.f.s. 

 During the late summer there is often no flow in the stream bed 

 below the lower dam, all the water being taken for irrigation. For 

 this reason Hurricane Creek is of no possible value to salmon. 



13U-(12). West Fork, Wallowa River . — (October 17, 1940; 

 Parkhurst and FreyTJ The West Fork joins the East Fork to form the 

 main Wallowa River approximately 1 mile above Lake Wallowa. It 

 extends for about 10 miles with a steep gradient through extremely 

 mountainous terrain to its source in several high mountain lakes. 

 The stream was 30 feet wide near the forks, very turbulent, and 

 flowing at an estimated rate of about 100 cf.s. at the time of the 

 survey. A waterfall 30 feet in height is located about \ mile above 

 the mouth. The short stream section below the falls is of some value 

 to land-locked blueback salmon. The greater portion of the stream is 

 of value only to resident trout. 



13U-(13). East Fork, Wallowa River . — (October 17, 19U0; 

 Parkhurst and FreyT) The East Fork joins the West Fork to form the 

 main Wallowa River about 1 mile above Lake Wallowa. It is a small, 

 turbulent stream extending for a distance of about 5 miles to its 

 source in a high mountain lake. An impassable power dam 8 feet in 

 height is located 1^ miles above the forks. At the time of the survey 

 the flow just above the power diversion was 11 c.f.s., of which 6 c.f.s. 

 were being delivered to the power plant 1 mile downstream, and 5 c.f.s. 

 were being by-passed. The tailrace of the power plant discharges into 

 the West Fork \ mile downstream. Gaging station records of the U. S. 

 Geological Survey for the years 192U-U5, taken at a station J mile above 

 the mouth and 1 mile below the power diversion show discharges ranging 

 from a maximum flood of 300 c.f.s. in July, x937, to a minimum of 

 0.1 c.f.s. (regulated) in December, 1929. The average discharge for 

 the 21-year period was 11,9 c.f.s. Gaging station records taken at 

 the power plant tailrace over the same period of years show discharges 

 ranging from a maximum of 17 c.f.s. to periods of no flow. The power 

 plant average discharge for the 21-year period of record was 7*56 c.f.s. 



The East Fork is of little possible value to fish other than 

 a few resident trout in the upper section. 



13V. Lookingglass Creek . — (October 9, 19U0j Parkhurst and Frey.) 

 Lookingglass Creek enters the Grande Ronde River approximately 8$ miles 

 above the mouth. It extends for a distance of about 16 miles to its 

 source in several springs. The stream was U3 feet wide near the mouth, 

 and was discharging approximately 80 c.f.s. at the time of the survey. 

 The gradient is moderate, with numerous shallow riffles, good resting 

 pools, and an abundance of excellent spawning area. The watershed is 

 uninhabited, and there are no obstructions or water demands on the stream.
