Show topped, gravel capped, sagebrush covered bench on the high left abutment. Revegetation of this area would be very slow. Open canal construction would require approximately 500 acres of land and road construction another 20 acres. Operation of this Unit would deplete the flows of the Colorado River by 45,000 acre- feet per year. This would increase the salt concentration of Lake Mead by 5 mg/ 1 at an estimated cost of $ 207,000 to downstream users each year. Summary of Major Impacts Table C- 30 presents the array of major environmental impacts that would result from implementation of the entire Central Utah Project. Source of the information is Bureau of Reclamation studies published and unpublished, ^ 0 with the following exceptions. Data for the columns " Big Game Habitat Lost," " Upland Game Habitat Lost," " Waterfowl Habitat Lost," " Fur Beaver Habitat Lost," and " Marsh Land Lost" were taken from reports of the Bureau of Sports Fisheries and Wildlife and the Forest Service. > 2,139,140 where sufficient data were unavailable, such as for the existing Vernal Unit and the proposed Ute Indian Unit alternatives, estimates were made by the Bureau of Reclamation. The anticipated impacts of the Units still in the planning stage would change where modifications in the plans are made. However, the impacts shown here are representative of those which would likely occur. 440 |
