Other Agencies with Actions or Authorizations: Department of the Interior, Fish and Wildlife Service Department of the Interior, Bureau of Land Management Department of the Interior, National Park Service Department of the Interior, Bureau of Indian Affairs Description: The LPP is a proposed 140-mile, 69-inch-diameter water delivery pipeline that begins at Lake Powell near Glen Canyon Dam in Page, Arizona, and ends at Sand Hollow Reservoir near St. George, Utah. The pipeline would deliver up to 86,249 acre-feet of water from Lake Powell to Sand Hollow Reservoir. UBWR proposes building the LPP in order to establish a second source of water to Washington and Kane Counties in Utah to meet future water demands, diversify the regional water supply portfolio, and enhance the reliability of the water supply. Two pipeline alignments have been proposed: the Southern Alternative and the Highway Alternative. Both alternatives begin and end in the same locations. The Southern Alternative would travel south of the Kaibab Indian Reservation. The Highway Alternative would cross lands held in trust by the United States for the benefit of the Kaibab Band of Paiute Indians, following Arizona State Route 389. Both proposed alternatives would cross federal, state, private, and tribal trust lands. In addition, UBWR has requested a water exchange contract with Reclamation wherein UBWR would forbear the diversion of a portion of the natural flows to which UBWR is entitled in exchange for depleting an equal amount of water released from Flaming Gorge Dam throughout the year and available at Lake Powell. This exchange contract would not entitle UBWR to call for releases from Flaming Gorge.
