Folsom Dam, located on the American River in Sacramento, California, is a key federal hydroelectric facility owned and operated by the Bureau of Reclamation. Completed in 1956, this concrete gravity dam stands at a towering height of 275 feet and has a structural height of 340 feet, providing essential water storage for irrigation, recreation, and hydroelectric power generation. With a storage capacity of over 1 million acre-feet and a surface area of 11,180 acres, Folsom Dam plays a crucial role in water resource management in the region.

The dam has undergone modifications in 2000 to enhance its foundation, hydraulic, seismic, and structural integrity, ensuring its continued safety and reliability. Despite being classified as having a high hazard potential, Folsom Dam is regularly inspected by the Bureau of Reclamation to uphold its operational standards. Additionally, the dam has an emergency action plan in place, meeting guidelines to effectively manage any unforeseen events. With Congressman Ami Bera representing the area, Folsom Dam remains a vital infrastructure for water supply, flood control, and energy production in the state.

In summary, Folsom Dam stands as a significant engineering feat that not only provides essential water storage and hydroelectric power but also contributes to irrigation and recreational opportunities along the American River. With its impressive storage capacity and structural design, coupled with regular inspections and emergency preparedness measures, Folsom Dam remains a critical asset in water resource management for the Sacramento region.
