| Relation | Central Utah Project; Western Waters Digital Library; CHAPTER II 11 alternatives alternative C alternative C corresponds with the iad lad system no action alternative and would be viable only if the iad i&d system were not built this alternative would provide for the transbasin trans basin diversion of water from the colorado river basin to the bonneville basin and would provide 3 MW of power for project pumping the alternative would also allow nonfederal non federal financing of an additional 67 MW of power and would satisfy requirements of the 1980 stream instream In flow agreement by reducing the transbasin trans basin diversion project features for this alternative are shown on the following map and elevation profile and summary data are presented in table 5a aa project features and measures including fish wildlife and recreation would be the same as for alternative A except as noted below monks hollow dam and powerplant Power plant would ie be deleted from the plan monks hollow switchyard and the transmission line from the switchyard to last chance switchyard also would be deleted the 138 kv bus tie bay would be deleted from last chance chanco switchyard A small diversion and regulating dam would be constructed at three forks approximately 10 miles upstream from the confluence of diamond fork and the spanish fork river three forks dam would bea be a roller compacted concrete structure 60 feet high with a crest length of 275 feet approximately 65000 yards of concrete would be used in the dam the entire crest of the dam would serve as a spillway to safely pass anticipated floods two outlet works would be provided an outlet to the intake for the diamond fork pipeline described below would have a capacity of 350 cfs cs the second outlet to the diamond fork stream channel would have a capacity of 250 cfs cs three forks reservoir would have a total capacity of 430 acre feet consisting of 300 acre feet of active capacity and 130 acre feet of dead storage for sediment accumulation at normal water surface elevation 5582 feet the reservoir would have a surface area of 14 acres the reservoir could fluctuate 27 feet on a daily basis to regulate daily peak releases from last chance powerplant Power plant the reservoir would have a surface area of 8 acres at minimum pool most of the sediment load would be flushed through the reservoir about 3 percent trap efficiency however occasional removal of some bedload material might be required to maintain proper operation roads would be the same as for alternative A except that an additional 2.7 27 27 miles of the diamond fork road would be upgraded between monks hollow damsite adamsite and three forks dam without nonfederal non federal financing last chance powerplant Power plant would be built to a capacity of 3 MW however the full capacity of 60 MW could be constructed with nonfederal non federal financing diamond fork powerplant Power plant could be constructed to a capacity of about 10 MW with nonfederal non federal financing but would not be built unless nonfederal non federal participation is involved total potential generating capacity 27 3 .3 BEST COPY AVAILABLE |
