Show 15 c. f. s. Minimum flows below the dam with the Unit would be 15 c. f. s. These flows would be maintained to Uintah Canal which is approximately 5 miles downstream. The State survey indicates that to maintain the classification in Whiterocks River below the dam, flows of 10 c. f. s. would be necessary. 73 The Forest Service has recommended minimum flows of 17 c. f. s. 109,140 The proposed plan calls for minimum flows of 7 c. f. s. in this section of the river below the dam. The 7 c. f. s. would be maintained downstream to the present irrigation diversions at Farm Creek and the Whiterocks Canal. Minimum flows below these points would depend on winter diversions through these canals for stock watering. The reduced streamflow would adversely affect approximately 11 miles of Uinta River and 7 miles of Whiterocks River. The proposed plan specifies that land supporting juniper would be chained and planted to forbes and browse to mitigate the loss of deer winter range in the Uintah Reservoir Basin. The land to be improved would involve approximately 600 to 700 acres, and would be located on the Uintah and Ouray Indian Reservation. Environmental assessments would be carried out to provide an inventory of species of plants and animals found in the Unit area. This inventory would be included in the Uintah Unit Environmental Statement. The Uintah Unit would deplete the flows of the Colorado River by an average of 30,500 acre- feet per year. The Unit would also increase the salt concentration at Hoover Dam by 3 to 5 mg/ 1. This would result in a cost to downstream water users of $ 124,200 to $ 207,000 per year. Ute Indian Unit The Ute Indian Unit would complete the development of the Central Utah Project by ( 1) serving all the additional supplemental irrigation water requirements in the Uinta Basin; ( 2) serving all the remaining Group 5 Indian land deferred under the other Units; ( 3) serving all anticipated municipal and industrial requirements in the Uinta Basin; and ( 4) diverting Utah's remaining share of Colorado River water to the Bonneville Basin for future municipal and industrial needs. Planning personnel of the Utah Division of Water Resources are considering the alternative use of this water for development of steam- generated electrical power. Since a final determination has not been made, two alternatives are described in this statement. The maximum development represents the four goals above. 423 |
