The Biden-Harris administration October 19 announced next steps in the formal process to develop future operating guidelines and strategies to protect the stability and sustainability of the Colorado River system and strengthen water security in the West. The guidelines under development would be implemented in 2027, replacing the 2007 Colorado River Interim Guidelines for Lower Basin Shortages and the Coordinated Operations for Lake Powell and Lake Mead, which are set to expire at the end of 2026.
