Show Little Cottonwood Creek would only be affected near the mouth of the canyon where increased direct diversions would take place. This would leave smaller flows in the creek from there to the Jordan River. Some of the increased direct diversions would be obtained from conversion of existing irrigation water rights to municipal water uses. Flows in sections of streams to be affected have been intermittent. The Class III fishery further upstream would not be affected. The collection and distribution systems associated with the Corps of Engineers Little Dell Project would leave construction scars and spoil areas from the tunnel and pipeline excavation. Flows from Emigration Creek, which supports a Class IV fishery, would be diverted to Little Dell Reservoir any time they exceed one c. f. s. The small flow left in Emigration Creek would not be adequate to support a stream fishery. The flow of approximately 6 miles of Emigration Creek would be decreased. A minimum flow of 2 c. f. s. would be maintained in Mill Creek below the diversion point. The flow in 5* 9 miles of this Class III fishery stream would be reduced to the minimum above. Little Dell Reservoir would inundate about 1.6 miles of Dell Creek, resulting in a loss of Class III stream fishery. About 325 acres of wildlife habitat would be inundated by the reservoir, as well as 1^ miles of the Mormon Trail, the Pony Express Trail, and the Little Dell Pony Express Station, a designated national historic place. Also requiring relocation would be a Girl Scout camp and the Ephraim Hanks Pony Express Station marker. Construction of Little Dell Reservoir would create a recreation area within a short distance of Salt Lake City and would develop a municipal water supply to be used in Salt Lake County to satisfy increasing demands. Below Little Dell Dam flow would be reduced in about a mile of the stream. Also, flows would be reduced in 9 miles of Parley's Creek, which supports a Class III fishery, and flows would be increased in 2 miles of Parley's Creek and about 1.5 miles of Lambs Creek, both Class III fisheries. The development of water supplies from the Wasatch Front streams would decrease the water contributed to recharge of the groundwater reservoir. Flows into Jordan River and through a 20- mile reach of Class V fishery and the waterfowl areas at the mouth of Jordan River would be decreased. City Creek would remain the same as it is at the present time. 506 |
