Proposed Lake Mead Intake No. 3
Lake Mead National Recreation Area » Proposed Lake Mead Intake No. 3 » Document List
The Southern Nevada Water Authority (SNWA) is proposing to construct a third water supply intake, Intake No. 3, in Lake Mead. Project components include an intake pumping station on Saddle Island, intake tunnel, forebay, conveyance pipeline to the existing Alfred Merritt Smith Water Treatment Facility, access roads, staging areas, and other associated project elements.
SNWA is the regional water supply entity for the Las Vegas metropolitan area. The project is needed to protect the community's existing water supply system capacity against the potential loss of Intake No. 1's pumping capability should lake levels fall below 1,050 feet above mean sea level. Water levels in Lake Mead have fallen during the recent drought on the Colorado River, and long-term projections for river flows point to a continued decline in lake water levels.
The environmental assessment examines in detail two alternatives: no-action and proposed project. The proposed project is described above, while the no-action alternative represents a continuation of existing conditions- no new intake would be constructed, and the two existing water supply intakes in Lake Mead would continue to operate under declining long-term lake level conditions. The EA analyzes the alternatives and their impacts on the human and natural environment, in accordance with the National Environmental Policy Act (NEPA) of 1969, the regulations of the Council on Environmental Quality (CEQ) (40 Code of Federal Regulations [CFR] 1508.9) and NPS Director's Order-12.
