Before the end of 2026, the U.S. Secretary of the Interior will develop new guidelines for the long-term management of the Colorado River system. The Colorado River Basin States will play a leading role in the process to develop those new guidelines. The process will take many years and require multiple levels of discussion, negotiation and coordination within Arizona and among the Basin states.

To ensure Arizona remains stronger together, the Arizona Department of Water Resources and Central Arizona Project are beginning now by reconvening the Lower Basin Drought Contingency Plan (LBDCP) Steering Committee delegates to form the Arizona Reconsultation Committee (ARC). This committee will develop an Arizona perspective on the reconsultation of the Colorado River Interim Guidelines for Lower Basin Shortages and the Coordinated Operations for Lake Powell and Lake Mead, known as the 2007 Guidelines.
