Show Duchesne River and 0.6 mile above the U0S0G# S0 Gaging Station No. 9- 2735. Flows up to the 30- c. f. s. capacity of the inlet structure would be diverted to the aqueduct. Average October to March winter accretion flows below the diversion would be expected to be about 1.6 to 3.2 c. f. s., although minimum recorded flow at the gage has been zero at times during 1965 and 1961. The proposed annual diversion from Hades Creek is estimated to be 4,800 acre- feet. An estimated 100 acre- feet would be bypassed for downstream rights and an additional 1,700 acre- feet spilled during the high runoff period. No recommendation for minimum fishery bypass was submitted for this section of Class III stream. It would be expected that Unit operation would virtually eliminate this 0.6 mile of habitat. ( e) Wolf Creek and Twin Creek Strawberry Aqueduct would intercept Wolf Creek at a point 3.0 miles above the confluence with the West Fork of Duchesne River and 0.6 mile above U. S„ G„ S. Gaging Station No. 9- 2760. Twin Creek would be intercepted at a point 1,000 feet above the confluence with Wolf Creek and U. S. G. S, Gaging Station No. 9- 2760 on Wolf Creek. Flows up to the 25- c. f. s. capacity of the diversion structure on Twin Creek would be diverted to the aqueduct - The average October to March winter flows combined for the two streams at the aqueduct, based on area- altitude runoff studies, would be expected to be in the 3.2- to 6.5- c. f. s. range. There are springs that emerge on Wolf Creek about 500 feet downstream from the diversion site which contribute an estimated 1 c. f. s. to the stream. Twin Creek does not support a fishery habitat and is dry most of the year below the proposed diversion site. Tributary inflows to Wolf Creek should result in a 1- to 2- c. f. s. flow in Wolf Creek at the gage 310 |
