Bureau of Reclamation November 2022 – Federal Register Recent Federal Regulation Documents

The Secretary of the Interior has directed the Bureau of Reclamation (Reclamation) to prepare a Supplemental Environmental Impact Statement (SEIS). The Supplement is to the December 2007 Record of Decision entitled Colorado River Interim Guidelines for Lower Basin Shortages and Coordinated Operations for Lake Powell and Lake Mead (2007 Interim Guidelines). The Secretary is directing this action because the existing operating guidelines are insufficient given current hydrology and reservoir conditions and in light of plausible low runoff conditions in the Colorado River Basin over the next four years. Through this Federal Register notice, Reclamation is providing an overview of the purpose and need for the SEIS, as well as its anticipated approach and timeframe for decisions on revised operating guidelines for Lake Powell and Lake Mead.
