The Department of the Interior announced that it is initiating the formal process to develop future operating guidelines and strategies for the Colorado River.
The new guidelines will replace 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.
The public process will gather feedback for the next set of operating guidelines, including new strategies that take into account the current and projected hydrology of the Colorado River Basin.
The Basin is currently facing a historic drought, driven by climate change, that is increasing the likelihood of warming temperatures and continued low-runoff conditions, and therefore reduced water availability, across the region.
"Developing new operating guidelines for Lake Powell and Lake Mead is a monumentally important task and must begin now to allow for a thorough, inclusive and science-based decision-making process to be completed before the current agreements expire in 2026," said Reclamation Commissioner Camille Calimlim Touton. "The Bureau of Reclamation is committed to ensuring we have the tools and strategies in place to help guide the next era of the Colorado River Basin, especially in the face of continued drought conditions.”
The announced process is separate from the recently announced efforts to protect the Colorado River Basin through the end of 2026. The Supplemental Environmental Impact Statement to revise the December 2007 Record of Decision will set interim guidelines through the end of 2026; the process announced today will develop guidelines for when the current interim guidelines expire.
The Notice of Intent (NOI) to prepare an Environmental Impact Statement asks the public to consider the past 15 years of operating experience since adoption of the 2007 Interim Guidelines, as well as how the best-available science should inform future operational guidelines and strategies that can be sufficiently robust and adaptive to withstand a broad range of hydrological conditions.
The NOI also asks the public to consider how and whether the purpose and elements of the 2007 Interim Guidelines should be retained, modified, or eliminated to provide greater stability to water users and the public throughout the Colorado River Basin. The NOI will be available for public comment until August 15, 2023.
