Show Attendant with the construction of Hayes Reservoir would be the relocation of about 6 miles of existing road. Such construction would result in the removal of about 100 acres of existing vegetative cover and disruption of faunal habitat. Scarring of the landscape would also result. The borrow area for construction materials would be located primarily within the reservoir basin. The annual drawdown of water would expose some of this area and contribute to the adverse esthetic impact that would already exist. Exploration for riprap for Hayes Dam has not been completed. General geological studies suggest that suitable materials could be obtained downstream from the reservoir. Removal of this material could have adverse impacts on the stream channel. During construction of this feature there would be the usual esthetically undesirable noise and dust levels associated with construction. Turbidity of the creek would be temporarily increased. Normal behavioral patterns of animals and birds would be disrupted. Mona Reservoir Enlargement The surface area of Mona Reservoir would be enlarged from about 1,600 acres to 3,000 acres by the construction of a dam. ( See Figures A- 23 and A- 24). The inundated land would include about 640 acres of pheasant habitat along Currant Creek within the 2.0 miles between the reservoir and Burraston Ponds. Included in this acreage would be about 50 acres of Utah Divisionof Wildlife Resources land which is managed primarily for pheasants..- Inundation losses would occur initially but would be offset by habitat production or newly irrigated lands. A net habitat gain of about 12,500 acres would be expected. According to the Bureau of Sport Fisheries and Wildlife,* the increased marshy area produced by the enlargement would be used as a resting area for migrating birds and would slightly increase production of Canada geese by virtue of the increased peripheral habitat. The enlargement would also inundate the fishery in the 2.0- mile reach of Currant Creek between the reservoir and Burraston Ponds. This section of stream is not classified as a fishery in the State's inventory and classification of fishing waters.^ 3 264 |
