Show the proposed Wasatch Aqueduct for project uses as described in the Definite Plan Report. This alternative would cost more for both construction and annual pumping expenses than the Diamond Fork Power System plan. In addition, 6l, 000 acre- feet of Strawberry Valley Project water available under the Diamond Fork plan would not be available for power generation under this alternative. Consequently, power generation under the alternative would be about 30 percent less, even though the power heads are similar. ( b) Present Environment The present environment for the area affected by this alternative has been described for the proposed Bonneville Unit ( Sec. B), except for the Round Valley Power System and the pipeline from Provo River south to Wasatch Aqueduct. The power system would extend from Strawberry Reservoir through Round Valley into the existing Deer Creek Reservoir. The Wallsburg Tunnel No. 2 would exit into the mountainous area southeast of Wallsburg. This area is covered with native vegetation consisting mainly of aspen, conifers, oakbrush, sagebrush, and grasses. Wallsburg Powerplant would be lower in elevation, near the entrance of Main Creek into Round Valley. Vegetation in this area is mainly sage and oakbrush, with some willows and trees along the creek. The pipeline around the west side of Round Valley would traverse an area covered with grasses, sage, and oakbrush. Hanks Powerplant would be located on the edge of Round Knoll Reservoir in a sagebrush area. The area around the fringes of the reservoir would consist primarily of sagebrush, with meadowland in the basin and willows along Main Creek. Round Valley is generally used for cattle- type farming operations, with grazing lands, meadow pasture, and small irrigated fields around the town of Wallsburg. The area traversed by the pipeline from Provo River to the south end of Utah County would be along the base of the Wasatch Mountains. Vegetation there is mainly brush and grasses. Several roads and other public utilities traverse the same area. Also, heavily populated areas are in close proximity to the pipeline alinement. ( c) Environmental Impacts of the Alternative An open channel would be required from the minimum water surface elevation of Strawberry Reservoir to the inlet of Wallsburg Tunnel No. 1. This channel would be about 3 miles long and would parallel a portion of 589 |
