Show ( elevation 1+ 200), would be located on meadow- hay land and pastureland. The environment along pipelines required to convey water to Salt Lake Valley would be the same as described above for the Weber River importation. Water quality samples have been taken on the Bear River at Border, Wyoming, which is downstream from the upper diversion facilities. Dissolved solids at this station ranged from 268 to U72 mg/ 1, which is below the maximum U. S. Public Health Service requirements for drinking water. This water could be used directly in Salt Lake County for municipal purposes. The water from the lower Bear River has a much higher total- dissolved- solids content. The data obtained from the Corrine, Utah, station range from 356 to 2960 mg/ 1, with an average of about 600 mg/ 1. Water from the river at this point would not meet Public Health Service requirements for drinking water. This water would be used for irrigation in Weber County, and the higher quality Weber River water now being used for irrigation in Weber County would be diverted to Salt Lake County for municipal uses. ( c) Environmental Impacts of the Alternative The high- level diversion from the Bear River would have the following environmental impacts. Yellow Creek Reservoir would inundate about 15 miles of Yellow Creek and its live stream tributaries and about 5> 500 acres of land. Yellow Creek has very small flows during part of the year and is not a quality stream fishery. Fishery releases could be made from the new reservoir to maintain a year- round stream fishery. The reservoir on West Fork would inundate about 2 miles of the stream fishery and about 500 acres of land used for summer range by deer. Enlargement of Woodruff Narrows Reservoir would inundate an additional 3.6 miles of the Bear River stream fishery and 350 acres of meadow- hay land and pastureland. Ashby Reservoir would inundate about 2.5 miles of Smith's Fork, a good trout fishery. A diversion dam and canal with a short open- cut section 50 feet deep would be required to divert water into Yellow Creek Reservoir. Water releases in Yellow Creek could cause some erosion above the reservoir, requiring riprap protective measures. The high- level transfer water 542 |
