Notice of availability of a draft environmental impact statement and public hearings for the proposed adoption of Colorado River Interim Surplus Criteria: INT-DES 00-25.


Pursuant to Section 102(2)(C) of the National Environmental Policy Act (NEPA) of 1969, as amended, and the Council on Environmental Quality's Regulations for Implementing the Procedural Provisions of NEPA, the Bureau of Reclamation (Reclamation), has issued a Draft Environmental Impact Statement (DEIS) on the proposed adoption of specific criteria under which surplus water conditions may be determined in the Lower Colorado River Basin during the next 15 years. Cooperating agencies are the National Park Service and the International Boundary and Water Commission, United States Section. Information on public hearings may be found below in the DATES section.

If you wish us to withhold your name and/or address, you must state this prominently at the beginning of your comment. We will make all submissions from organizations or businesses, and from individuals identifying themselves as representatives or officials of organizations or businesses, available for public disclosure in their entirety.

The Secretary of the Interior (Secretary) currently manages the lower Colorado River system in accordance with federal law (including the provisions of the 1964 U.S. Supreme Court decree, as supplemented, in Arizona v. California (the Decree)), the Colorado River Basin Project Act of 1968 (CRBPA) and Long Range Operating Criteria (LROC) pursuant to the CRBPA. Within this legal framework, the Secretary makes annual determinations regarding the availability of surplus water from Lake Mead by considering various factors, including the amount of water in storage and predictions for natural runoff. The Decree provides that if there exists sufficient water available in a single year for release from Lake Mead to satisfy annual consumptive use in the states of Arizona, California, and Nevada in excess of 7.5 million-acre feet, such water may be determined by the Secretary to be made available as surplus water.

The purpose of and need for establishing interim surplus criteria is to assist the Secretary in making annual determinations of surplus conditions, and will afford entities that have contracted for surplus water a greater degree of predictability with respect to the annual existence of surplus water available for diversion. This greater predictability would assist these entities in the management of their water resources.

The DEIS presents four possible alternatives for implementation, plus a “No Action Alternative.” The DEIS does not include a preferred alternative. The interim surplus criteria alternatives have been formulated to be consistent with applicable federal law and the LROC, described above.

The four potential action alternatives are: a “Flood Control Alternative,” which would provide surplus water only when flood control releases from Lake Mead are needed, based on the current criteria for making such releases; the “Six States Alternative” and “California Alternative,” both of which specify various Lake Mead water surface elevations to be used as “triggers” to indicate when surplus conditions exist; and the “Shortage Protection Alternative,” which would permit surplus conditions to be determined above a specific elevation positioned to ensure enough water remains in Lake Mead to provide a one-year water supply to Arizona, California, Nevada, and Mexico, and to protect against dropping the lake's water level below a specified elevation.
