'. 0396 . . .\, " Environmental Effects BuRec has estimated that full development of CRSP would increase the salinity of the Colorado River as measured at Imperial Dam in Arizona by 147 milligrams/liter. The features which cause the majority of this increase are Glen Canyon Dam, Bonneville Unit of the Central Utah Project, Navajo Indian Irrigation Project, and San Juan-Chama. In addition to increasing Colorado River salinity, several CRSP developments threaten the habitat of two endangered species--the Colorado River squawfish and the humpback sucker. These fish are listed on the federal endangered species list and State of Colorado endangered species list, respectively. Two important birds on the federal endangered species list, the bald eagle and the peregrine falcon, range in the region of the Bonneville Unit of the Central Utah Project (CUP), a focus of the Inspector General's audit. Construction and operation of Bonneville will result in the loss of a substantial amount of high quality fish and wildlife habitat. Bonneville's municipal and industrial water features alone will destroy approximately 3,500 acres of wildlife habitat. Finally, significant reductions in flows in about 100 miles of waterway will occur, sometimes dropping belOW minimums recommended for fishery maintenance. Project Status at the Time of the Audit At the time the audit work began in September 1977, CRSP storage units were 95% complete and the participating projects were 22% complete. CUp's Bonneville Unit was l8% complete. Current Project Status As of January 1984, the four storage units were complete and the participating projects were approximately 62% complete. The Bonneville Unit was 26% complete and BuRec anticipated completion of the unit in 1993. Project Beneficiaries Hydroelectric power from CRSP (6 billion kilowatt hours annually) is dedicated first to pumping project water. 7he remaining power is sold by the Western Area Power Administration (WAPA) to preference customers in Colorado, New Mexico, Utah, Wyoming, Arizona, and parts of Nevada and California. Table 8-2 contains a listing of the major purchasers of CRSP power. The Central Utah ,later Conservancy District (CmICD), which has contracted for the water from the Bonneville Unit, will be the largest customer for water used to serve irrigators, municipalities, and industry in the four states of the upper basin. 81
