Camanche Main is a crucial water resource infrastructure located in San Joaquin, California, along the Mokelumne River. Completed in 1964, this rockfill dam stands at a height of 171 feet and has a storage capacity of 417,000 acre-feet, serving primarily as a water supply source. The dam also fulfills various purposes such as flood risk reduction, hydroelectric power generation, and recreation.

Managed by a public utility and regulated by state agencies like the Department of Water Resources and Safety of Dams, Camanche Main is subject to regular inspections by the Federal Energy Regulatory Commission to ensure its structural integrity and safety. With a spillway width of 400 feet and a high hazard potential, the dam has a moderate risk assessment rating. Despite its age, the dam's condition assessment is currently unavailable, highlighting the need for ongoing monitoring and risk management measures.

Camanche Main plays a vital role in water supply management and environmental conservation efforts in the region, supported by federal and state regulations to ensure its safe operation. As a key component of the water infrastructure in California, the dam's significance extends beyond its primary purpose, making it a critical asset for water resource and climate enthusiasts to monitor and advocate for sustainable water management practices in the face of changing climate conditions.
