A diversion dam ? feet in height is located approximately 

 3 miles above the mouth» There was a good flow over the crest of 

 this structure, and it was not a barrier to fisho About 3 c.f.So 

 were being diverted into an unscreened ditch for irrigation and stock 

 vvateringo 



Section (2) - Pine Valley ; 



Above the lower canyon section the stream extends for the 

 next 12 miles through Pine Valley to the town of Carson, In the 

 lower half of this section the stream flows through a valley char- 

 acterized by a series of low, rolling hillocks, which gradually re- 

 cede as the valley becomes wldero The gradient is moderate, and 

 gradually decreases upstreamo The stream divides about 15 miles 

 above the mouth, just above the village of Pine, The branch enter- 

 ing from the south side of the valley was discharging about l5 c.f,s,, 

 while the main stream above -Uiis point was flowing about 30 c,f,3« 

 at the time of observation, and in many places did not fully cover 

 the wide, shallow channelo The average width of the main stream 

 was about 30 feet© There su:e numerous excellent shallow riffles 

 throughout, and it was estimated that about 90 percent of the bottom 

 constituted suitable salmon spawning area. There are few resting 

 pools. In the upper half of this section the stream extends for a 

 distance of 6 miles through a gently sloping valley one to two miles 

 wide. This portion of the valley is extensively cultivated, and there 

 are large numbers of small, imscreened irrigation diversions, which 

 in late summer tsike practically all of the water in both the main 

 stream and the side channel. 



Section (3) - Carson to Cornucopia, Oregon; 



Above Pine Valley the stream extends for the next 5 miles 

 through a narrow valley 300-100 yards wide to the raining camp of 

 Cornucopia, There is no cultivation in this section. There was no 

 mining along the stream at the time of observation and, although 

 there has been considerable such activity in the past, the stream 

 has not been damaged. The gradient is moderate, increasing to fairly 

 steep upstream. There are no obstructions or diversions in this 

 portion of the stream. A side channel originates a mile above Carson, 

 and was carrying about 30 c,f,s, down the south side of Pine Valley, 

 The main stream was 39 feet wide and flowing about 90 cf.s, at 

 Cornucopia, The water temperature was 52,0 Fe There are numerous 

 excellent shallow riffles, and it was estimated that about 75 percent 

 of the bottom constituted suitable saLnon spawning area. Resting 

 pools are adequate and of good quality, especially in the upper part 

 of this section. 



Section (U) - Cornucopia, Oregon to headwaters : 



Above Cornucopia the main stream courses through a narrow 

 rocky canyon for a distance of about 2j miles. The gradient is 

 steep, the stream being of the cascade type. At this point the 

 main stream is formed by the confluence of the West Fork and the 

 Middle Fork, The bottom contains a large amount of bedrock and
