Show would be made from the canal to Mona Reservoir. Water from Mona Reservoir would be pumped back into the canal system and would eventually reach Sevier Bridge Reservoir. Thus, there would be a water connection between the Upper Bonneville Basin and the Lower Bonneville Basin ( Sevier River Basin) which are presently separated. However, it would not be likely that fish would survive passage through the pumps. Concern has been expressed that the gene pools of populations of leathers ids chubs and bullhead minnows, inhabiting the Sevier Bridge Reservoir, would be jeopardized by the operation of the Bonneville Unit. 66 The habitat losses produced by the Unit should not cause any game or nongame species to become rare or endangered. Stream Fisheries^ Inundations of about 39 miles of stream would eliminate the existing stream- dwelling species and the resulting dams and reservoirs would constitute barriers to migrating fish. This latter impact would not be expected to seriously affect fish populations because the species concerned do not require long migrations to complete their life cycles. The impacts of the Unit on streams has been more completely discussed previously in paragraph C3c. Reservoir Fisheries Presently there are over 200,000 acres of reservoirs in Utah. 73 Construction of the Bonneville Unit would add about 20,000 acres to this total. With the exception of the Strawberry Reservoir enlargement ( an increase of about 9,000 acres), development and maintenance of the fishery value of the propesed impoundments would have problems,, If a trout fishery was to be maintained then it would be necessary to stock the reservoirs annually with hatchery fish since trout require stream habitat in which to spawn and have the deposited eggs successfully incubated. 350 |
