Document Description
California American Water is proposing to modify the existing low-level regulating outlet at the Los Padres Dam and Reservoir in Monterey County, California. The proposed project is intended to accomplish the following three primary goals: 1) meet the California Department of Water Resources Division of Safety of Dams mandated requirement to drain the reservoir in case of emergency; 2) supply water to the Carmel River during low-flow summer months to meet instream flow requirements and sustain aquatic organisms, including South Central California Coast Steelhead; and 3) restore water supply to the existing fish trap and ladder necessary to provide upstream fish passage to adult steelhead. Achieving these goals are essential for restoring the original purpose of the outlet and reliably achieving existing environmental mandates regarding sustaining aquatic organisms within the Carmel River and providing upstream fish passage at Los Padres Dam. The proposed project includes the following components:
1. Site preparation and access improvements
2. Relocation of the upstream entrance
3. Replacement of emergency outlet valves
4. Installation and connection of new pipeline to existing pipeline
5. Site restoration and demobilization
Project construction is anticipated to begin in fall 2023, with completion in late 2024.
