Show Present Environment The present environment of the collection facilities in the Uinta Basin and conveyance facilities in the Bonneville Basin, with the exception of the Wallsburg Tunnel and Round Valley Conveyance System, are the same as in the proposed plan. Round Valley is a saucer- shaped valley, located southeast of Deer Creek Reservoir, and is about 11 miles long and 3 miles wide. The higher mountains on the south and west have stands of aspen, conifers, oakbrush, and grasses. The lower elevations have sagebrush, oakbrush, and grasses. The foothills are vegetated with sagebrush and grasses, with the bottomlands consisting of meadow pasture and small irrigated farms. Main Creek traverses the length of the valley and empties into Deer Creek Reservoir. The area is used for livestock pasture at the lower elevations and summer grazing for livestock and big game at the higher elevations. Wallsburg, a small farming community of 210 population, is located in Round Valley. Environmental Impacts of the Alternative The environmental impacts of features from Rock Creek down through the enlarged Strawberry Reservoir would be the same for this alternative as those described in the proposed Bonneville Unit plan. Patterns of water delivery from Strawberry Reservoir would be different from those of the Diamond Fork Power System as described for the proposed Bonneville Unit plan. Environmental impacts of the Round Valley System in this alternative would also differ from those of the Diamond Fork Power System in the proposed plan. The open channel from Strawberry Reservoir minimum water surface level to the inlet of Wallsburg Tunnel would be about 3 miles long and would require extensive excavation parallel to a portion of U. S. Highway kO. The channel would be exposed periodically as the reservoir water surface fluctuated. About 2 miles of the Strawberry River would be affected by both the increased reservoir water level and the excavation of the intake channel. Materials from the channel would be disposed of in the reservoir basin and spread so as to blend with the natural terrain. The excavation would be accomplished by sloping and rounding to minimize its visual effect on the natural area. Construction would cause sediment to enter Strawberry River and the reservoir unless preventive measures were taken. Materials excavated from Wallsburg Tunnel would be deposited in the area adjacen to Main Creek. Settling ponds would be required to reduce the sediment in Main Creek caused by 563 |
