| Relation | Central Utah Project; Western Waters Digital Library; CONSULT consultation AT A T L ON ll 11 AND A ND coordination continued JL 162 comment in conclusion I 1 find the environmental analysis for th this is project to be lacking the detail to present a true picture of the project this docu ment does not comply with the national environmental policy act or execu execl tive orders 11988 or 11990 response the scope of the diamond fork power system environmental statement covers in detail the production of hydroelectric power and the conveyance of bonneville unit water from the uinta basin to the bonneville basin im pacts for the overall bonneville unit are being analyzed in accordance with the format identified in the 1973 bonneville unit FES see response to comment no 131 thus reclamation has followed all required pro cedures cedores to fully comply with NEPA as well as executive orders 11988 1198 8 and 11990 all impact analyses emphasize consideration offlood offlook of flood plains and wetlands comments from barrie marchants marchands Mar chants letter of august 2 1983 163 comment in the EIS it is claimed that there will be small positive impacts upon the spanish fork river primarily due to year round flows in section 4 of that river currently section 4 is de watered annually and increased flows in the river as a whole As you know the spanish fork channel is extremely unstable the extreme differences between high summer flows and low winter flows combined with poor land use practices has resulted in unstable banks poor pool structure and a lack of spawning habitat under current proposals fluctuations in flow will be intensified over present 1 levels leveis at the same time water coming from strawberry reservoir will be much cleaner as it will not have picked up a silt load f from fron rom diamond fork As a result of these two factors the water will have increased ability to erode the streambed stream bed of the spanish fork river thus perhaps changing the nature of the riverbed riverbee river bed and invalidating predictions made regarding the fishery response fishery projections under project conditions have been revised to reflect the increased streambed stream bed erosion potential in the spanish fork river eroding streambanks stream banks however was only one of nine trout habitat param eters used in the analysis of impacts conducted by the interagency team of biologists consideration of all factors resulted in the fishery benefits presented in the FES reaches 2 and 3 would have substantial fisheries enhancement over historically dewatered watered dewaterer de conditions while adverse f fishery impacts would occur in reaches 4 and 5 primarily as a result of increased water velocities the reduction in turbidity may result in some increase in erosion however the most significant cause of any potential erosion would be higher f flow low volumes in the channel under project conditions spanish fork river flows would increase by about 5 to 25 percent on an average annual basis 312 |
