| Relation | Central Utah Project; Western Waters Digital Library; CHAPTER IV AFFECTED environment AND environmental consequences environmental impacts recommended PLAN the construction of monks hollow syar and sixth water reservoirs would inundate flood plains and cause the complete loss of 46 acres of existing stream and associated riparian vegetation through inundation these reservoirs would provide 393 acres of aquatic habitat in exchange in addition 28 acres of riparian vegetation would be temporarily dis turbed as a result of construction of the diamond fork pipeline from monks hollow dam to the spanish fork river u executive orders 11988 flood plains and 11990 wetlands were writ ten with the intent of minimizing flood damages and preserving the nat ural values of wetlands the minimization of flood damage in the diamond fork system is not an issue in this case because these facilities would be built for no other purpose than water conveyance and power production under these conditions flows in the streams would for the most part be controlled and the potential for flooding would be reduced A certain amount of flood control hasbeen hasteen has been included in the design capacity of monks hollow reservoir the natural values of wetlands within the project area would be diminished by project construction and operation the beaver is the best representative of the wetland value associated with the riparian woodland vegetative community the net change in habitat values would be 8 habitat units for this alternative but this loss would be partially or totally negated depending on which mitigation option was chosen the slight loss in value associated with some options is not considered to be significant to the wetland value of the riparian woodland habitat the loss of wetted streambed stream bed and associated macroinvertebrate macro invertebrate communities benthos would be relatively small 10 acres this loss would be traded for a macroinvertebrate macro invertebrate community associated with the reservoirs which would certainly be different in its species composition but would also have its own unique value however direct compensationenhancement compensation enhancement for the loss of the stream benthic communities as well as fisheries would occur on the lower diamond fork as described in chapter 111 III lii the temporary disturbance to wetland habitat values in diamond fork canyon from construction of the diamond fork pipeline would be minor when the pipeline is buried however at least 75 percent of the existing wetland values inherent in the riparian zone of the stream would be restored through mechanical revegetation and time the transmission lines and switchyards switch yards may have some impacts on flood plains and wetlands depending on designs flood plains and wet lands would be avoided wherever possible by spanning narrow canyons if project transmission facilities are designed to be constructed in a flood plain or wetland western would prepare a flood plainswetlands plains wetlands assessment which would recommend appropriate mitigation measures 112 |
