Berryessa Snow Mountain National Monument Expansion Act

S 683, the Berryessa Snow Mountain National Monument Expansion Act, adds approximately 3,925 acres of Federal land (the Walker Ridge Addition) to the Berryessa Snow Mountain National Monument in Lake and Colusa Counties, California. The bill designates this area as "Condor Ridge (Molok Luyuk)" using the Patwin language, updating all federal references to the parcel. It requires the Secretary of the Interior to administer the expanded area under existing monument rules, including mandatory consultation with affected federally recognized tribes during management planning and ongoing decision-making. The bill also mandates a joint management plan within one year of enactment and ensures tribal input through existing federal partnership authorities.
