Owens Dam, located in Mariposa, California, is a federally-owned structure managed by the US Army Corps of Engineers. Completed in 1949, this earth dam stands at a height of 72 feet and serves primarily for flood risk reduction and hydroelectric purposes along Owens Creek. With a maximum storage capacity of 6,064 acre-feet and normal storage of 4,138 acre-feet, the dam covers a surface area of 175 acres and has a drainage area of 26 square miles.

This high-hazard potential dam features an uncontrolled spillway, with a spillway width of 75 feet, and has a history of periodic inspections to ensure its structural integrity. The USACE actively manages dam-related flood risks by monitoring its condition, conducting maintenance and repairs as needed, and working closely with local emergency managers to develop emergency action plans and evacuation procedures. Despite the risks associated with flood events and dam releases, the USACE is dedicated to mitigating these risks and ensuring the safety of downstream communities. Additional details specific to the risk management measures for Owens Dam will be provided in the future to enhance public awareness and preparedness.
