7U. South Fork, Burnt Pdver. — (September 27-30, 19U1; Parkhurst 

 and ZinmerT5 The South Fork enters Unity Reservoir approximately 2 miles 

 above the dam. It is about 16 miles long, and was surveyed for a dis- 

 tance of 13 miles to the mouth of Spring Creek, Above this point the 

 stream was flowing less than 2 c.f.So, and was considered too small to 

 be of amy possible value to salmon. The stream was l5 feet wide near 

 the mouth, and wa? discharging about iS c,f .So into the Unity Reservoir, 

 The mouth of the stream at the time of the survey was 1000 yards below 

 the high water level of Unity Reservoir. The volume of flow in the 

 stream channel varies widely at different points in the first 6| miles 

 above the mouth, due to the intake and return flows of numerous diver- 

 sions. The water temperature ranged from U9 F. at the mouth to U6 F, 

 at the upper terminus of the survey. From the mouth to Whited Reservoir, 

 a distance of about 6 miles, the gradient is slight to moderate, with 

 numerous small riffles smd well protected resting pools. The stream 

 bed is composed chiefly of medium and small rubble, and there is also 

 a large amount of silt. There were 18,000 square yards of suitable 

 spawning area, constituting approximately 2? percent of the total bottom 

 in this section. There are 8 irrigation ditches on the South Fork up 

 to ItVhited Reservoir, with a total water diversion of U8 cf.s. With 

 one exception, none of them have dams which might obstruct the passage 

 of fish. 



The Whited Reservoir Dam is of the earth embankment type, 

 approximately UO feet high and 75 feet long. The outlet extends 

 through the base of the dara, and is gate controlled. No fishways 

 are provided, and the dam is a total barrier to the upstream passage 

 of fish. The '"hited Reservoir extends about ^ mile upstream, and 

 has a maximum width of somewhat more than ^ niile. 



Above the Whited Reservoir Dam the stream extends for a distance 

 of 7 miles to the terminus of the survey. The gradient is moderate, 

 with numerous good shallow riffles and small pools. The stream oed is 

 composed chiefly of medium and small rubble, and there is much less 

 silt than occurs below. There were 146,000 square yards of s ui table 

 spawning area, constituting approximately $2 percent of the total bot- 

 tom in this section, 1'here are 6 irrigation ditches, with a total 

 water diversion of about 65 cf.s. There are no dams above Whited 

 Reservoir that are barriers to fish, 



7U-(1) Pole Greek . — (September 30, 19hl; Parkhurst and Zinmer,) 

 Pole Creek enters the South Fork of Burnt River approximately 5 miles 

 above the mouth. It is about 6 miles long, and was discharging less 

 than 1 cf.s, ^ere are 5 small irrigation ditches on the stream. 

 It is of no present or potential value to salnon, 



7U-(2)« Bullrun Creek , — (September 30, 19Ulj Parkhurst and 

 Ziramer.) Bullrun Creek enters the '^outh Fork of Burnt River approxi- 

 mately 8 miles above the mouth. The stream is about 7 miles long.
