Beardsley Dam, located in Sonora, California, is a key structure along the Middle Fork Stanislaus River designed by Tudor-Goodenough and completed in 1957 for hydroelectric power generation. This earth-type dam stands at a height of 278 feet, with a hydraulic height of 276 feet, and a structural height of 284 feet. With a normal storage capacity of 97,500 acre-feet and a maximum storage of 97,800 acre-feet, Beardsley Dam plays a crucial role in flood risk reduction, hydroelectric power production, and recreation in the region.

Managed by the Federal Energy Regulatory Commission (FERC), Beardsley Dam is under state regulation and inspection by the California Department of Water Resources (DWR) for its safety and compliance with state laws. The dam's spillway, with a width of 174 feet and controlled design, can handle a maximum discharge of 90,000 cubic feet per second. Despite its high hazard potential, the condition assessment for Beardsley Dam is currently not available, indicating a need for further evaluation and risk management measures to ensure its continued safety and functionality.

With its very high risk assessment rating and significant storage and discharge capacities, Beardsley Dam is a critical infrastructure for water resource management and climate resilience in the Tuolumne County region. As a public utility structure serving various purposes, including flood control and renewable energy generation, Beardsley Dam's operation and maintenance are essential for safeguarding the surrounding communities and ecosystems. Ongoing monitoring, inspection, and risk management efforts will be crucial in ensuring the long-term safety and sustainability of this vital water resource facility.
