Bear Dam, located in Mariposa, California, along Bear Creek, is a vital structure managed by the US Army Corps of Engineers for flood risk reduction and hydroelectric purposes. Completed in 1954, this earth dam stands at a height of 85 feet and has a storage capacity of up to 12,700 acre-feet. With a spillway width of 100 feet, the dam plays a crucial role in managing water levels and preventing potential flooding in the region.
Despite being classified as having a high hazard potential, Bear Dam is regularly monitored and maintained by the USACE to mitigate risks associated with severe weather events and ensure structural integrity. The emergency action plan for the dam is continually updated, and the agency collaborates with local emergency managers to develop evacuation plans and raise public awareness. Through ongoing risk management measures, USACE works to address all types of flood risk associated with the dam and maintain its operational efficiency for the safety and well-being of the surrounding communities.
