| Relation | Central Utah Project; Western Waters Digital Library; pumpback humpback pump back storage operation however it would involve only two power plants one of which would be an underground pumped storage plant in the fifth water reservoir and a 9800 acre foot monks hollow reservoir syar tunnel which would have a slightly different alignment in this plan would convey strawberry reservoir water through syar powerplant Power plant to fifth water reservoir during peak demand periods for power releases from fifth water reservoir would be made through an underground penstock to the fifth water underground powerplant power plant and discharge tunnel into monks hollow reservoir from this point part of the water would be reregula ted for downstream releases either directly to diamond fork up to 300 cfs cs or into the diamond fork pipeline up to 400 cfs cs to be conveyed directly to the spanish fork river during low demand periods for power water from monks hollow reservoir would be pumped back through the system to fifth water reservoir for reuse one underground surge chamber on fifth water discharge tunnel and a surge tank on syar tunnel most of which would be underground would be included to relieve rapid changes in pres pressure pressuria suril suria in the system b environmental impacts construction of the fifth water pumped storage alternative would provide an estimated 3840 jobs during the peak year and would provide about 151400000 in income over a 5 year construc construe con struc tion period operation and maintenance of the system would provide about 60 permanent jobs with a combined annual income of about 1160000 the principal impact of the fifth water alternative on water quality would be an overall reduction in sediment yield in diamond fork monks hollow reservoir would remove a large part of the sediment that presently originates above the monks hollow adamsite damsite and would reduce the sediment yield from diamond fork to the spanish fork river by about 44 percent or about 72 tons per day the serious erosion problem that now exists on the lower diamond fork would be reduced the fifth water alternative plan would provide essentially the same flows to sixth water creek diamond fork and the spanish fork river as the sixth water pumped storage alternative the impact of this alternative on the stream fisheries would be more beneficial than those described for either the DPR alternative or the sixth water alternative it is anticipated that no fishery mitigation measures would be necessary for this alternative other than the rehabili reh abili tation of the sixth water stream channel however since 1 the monks hollow reservoir would inundate only 1.5 15 15 miles of class 111 III lii stream fishery instead of 2.5 25 25 miles 2 there would be no sixth water reservoir to inundate stream fishery habitat and 3 the fifth water reservoir would inundate about 2 miles of fifth water creek a small stream having a limited trout fishery H 23 |
