San Antonio, a public utility located in Bradley, California, operates a dam on the San Antonio River for flood risk reduction, irrigation, and water supply purposes. The earth dam, with a height of 202 feet and a length of 1433 feet, was completed in 1965 and has a storage capacity of 350,000 acre-feet. The dam is under state regulation and inspection by the Department of Water Resources (DWR) and the Safety of Dams agency, ensuring its safety and compliance with state requirements.

The dam's hazard potential is considered high, but its condition assessment is fair as of April 2019. Regular inspections occur every year, with the last one conducted in November 2020. Although no major modifications or risk management measures are noted in the data, the dam's emergency action plan (EAP) status and adherence to guidelines are unspecified. With its strategic location in Monterey County and its pivotal role in managing water resources, San Antonio Dam serves as a crucial infrastructure piece for the region's water security and flood protection needs.

Represented within the San Francisco District, the dam stands as a key asset in the region's water infrastructure, with the potential to mitigate flood risks and provide essential water supplies for irrigation and other purposes. As climate change continues to impact water resources, the role of San Antonio Dam in ensuring water security and managing risks associated with natural disasters like floods becomes increasingly vital. Moving forward, ongoing maintenance, risk assessments, and adherence to regulatory standards will be crucial in safeguarding this essential piece of infrastructure for the community and the environment.
