Colorado River between dam to Lees Ferry
The Bureau of Reclamation has finalized its process to protect the short-term stability and sustainability of the Colorado River System by signing the Supplemental Environmental Impact Statement (SEIS) for Near-term Colorado River Operations Record of Decision. The Department of the Interior released the final SEIS in March 2024.
Reclamation initiated the supplemental environmental impact statement to protect Glen Canyon Dam and Hoover Dam operations, system integrity, and public health and safety. This supplemental guidance will be effective through 2026 – at which point the existing 2007 Interim Guidelines and the 2019 Drought Contingency Plans expire. This record of decision is a substantial milestone in the ongoing efforts to address water scarcity, the ongoing drought, and climate change challenges in the Colorado River Basin.
Reclamation’s action selected in this record of decision is the preferred alternative that the Department identified in March 2024, which will yield at least 3 million acre-feet of system water conservation savings through the end of 2026, coinciding with the expiration of the current guidelines, and provides additional tools to manage dry hydrology.
Selection of the preferred alternative was made possible through Reclamation’s collaborative efforts including those with the seven basin states, 30 basin Tribes, water managers, farmers and irrigators, municipalities, power contractors, non-governmental organizations, and other partners and stakeholders, and underpinned by historic water conservation enabled by President Biden’s Investing in America agenda.
