Don Pedro Main, located in La Grange, California, is a vital public utility structure on the Tuolumne River that serves multiple purposes such as hydroelectric power generation, irrigation, flood risk reduction, and recreation. Designed by Bechtel and completed in 1971, this earth dam stands at a height of 585 feet with a storage capacity of 2.3 million acre-feet and a surface area of 13,000 acres. Managed by the Federal Energy Regulatory Commission, the dam has a controlled spillway width of 1130 feet and three Tainter radial gates for water release.

Despite its high hazard potential, with a very high risk assessment rating, Don Pedro Main is closely monitored and inspected by state and federal agencies to ensure its safety and regulatory compliance. The dam is under the jurisdiction of the California Department of Water Resources' Safety of Dams division, with regular state inspections and enforcement activities in place. Additionally, the dam's emergency action plan is regularly updated, with a last revision date in December 2020, to meet guidelines and ensure preparedness for any potential emergencies.

With its significant role in water resource management and climate adaptation efforts, Don Pedro Main remains a critical infrastructure in California's water supply system. Its operational features, including a large storage capacity, controlled spillway, and multiple outlets, contribute to water supply reliability, flood control, and environmental conservation in the region. As water resource and climate enthusiasts, understanding the design, purpose, and regulation of structures like Don Pedro Main is essential for ensuring sustainable water management practices and resilience to future climate challenges.
