located 1 mile above the town of Lostine, or approximately 7 miles 

 above the mouth. This dam is not provided with a fishway, and is 

 passable to fish only at high water stages. The water diversion is 

 supplied by means of a well at one side of the dam, and does not 

 greatly reduce the flow. The Lostine River formerly supported good 

 runs of salmon, and it was reported to be of some present value to 

 steelhead trout. It is of considerable value to resident trouty 

 and also has a greater potential value for anadromous species . 



13U_(8). Parsnip Creek .— (Not surveyed.) Parsnip Creek enters 

 the Wallowa River approximately 30 miles above the mouth. It is a 

 small stream, and becomes almost dry in late summer* It is of no 

 possible value to salmon. 



13U-(9). Trout Creek. — (October 12, 19U0; Parkhurst and Frey.) 

 Trout Creek enters the Wallowa River about 2 miles downstream from 

 the town of Enterprise, or approximately Ul miles above the mouth. 

 It was discharging about 10 c.f ,s. at the time of the survey, but 

 the flow is greatly reduced during the late summer. The gradient is 

 moderate, and there is some good spawning area. Because of its small 

 size at the season of the Chinook salmon spawning migration, the 

 stream is of little possible value to this species. 



13U-(10). Prairie Creek . — (October 16, 19u0; Parkhurst and Frey.) 

 Prairie Creek enters the Wallowa River near Enterprise, Oregon, approxi- 

 mately Ul§ miles above the mouth. The stream extends for a distance of 

 about 1$ miles through the upper part of the flat Wallowa Valley, The 

 gradient is slight through the greater part of the cultivated portion 

 of the watershed, and the stream bed contains a large amount of mud and 

 sand. The stream was 27 feet wide near the mouth, and was discharging 

 about 30 c,f,s. at the time of the survey. Two large irrigation di- 

 versions originating on the Wallowa River a short distance downstream 

 from Lake Wallowa discharge their return flows into Prairie Creek, 

 accounting for the relatively high volume of flow in the lower section. 

 The stream contains some spawning area, but does not appear to be alto- 

 gether suitable for salmon. It is formed by a number of small tribu- 

 taries near the head of Lake Wallowa, all of which are too small to be 

 of value to salmon. 



13U-(11), Hurricane Creek , — (October 17, 19l|0j Parkhurst and 

 Frey,) Hurricane Creek enters the Wallowa River a short distance above 

 the mouth of Prairie Creek, near the town of Enterprise. The stream is 

 about 18 miles long, and has an average width of 25> feet. The gradient 

 is moderate to fairly steep, with numerous shallow riffles, adequate 

 resting pools, and excellent appearing spawning areas. Water measurements 

 taken at a point approximately 8 miles above the mouth, upstream from 

 all diversions, indicated a flow of about 60 c.f.s. at the time of the 

 survey. Records show that the flow at this point ranges from a minimum 

 of about 10 c.f.s, to a maximum of about 500 c.f.s. (Water Resources of the 

 State of Oregon.)
