Santa Fe Dam, also known as Santa Fe Reservoir, is a federal-owned earth dam located in El Monte, California.
Completed in 1949, the dam's primary purpose is flood risk reduction, with additional benefits including recreation and water supply. With a height of 92 feet and a maximum storage capacity of 45,409 acre-feet, Santa Fe Dam plays a crucial role in managing the San Gabriel River's flow and protecting downstream communities.
A risk assessment conducted in 2016 identified Santa Fe Dam as having a moderate risk level, particularly due to potential internal erosion of the embankment and impacts from earthquake events. The downstream cities of Irwindale, Baldwin Park, El Monte, and South El Monte, with a combined population of over 100,000, face significant economic and life-threatening consequences in the event of a dam failure. To mitigate these risks, the US Army Corps of Engineers (USACE) actively engages with state and local emergency managers, conducts emergency exercises, closely monitors the dam's condition, and collaborates with local communities to enhance emergency preparedness and communication.
Through ongoing risk management measures, including regular inspections, monitoring, maintenance, and stakeholder engagement, USACE is dedicated to ensuring the safety and resilience of Santa Fe Dam. By working proactively to address identified risks and enhancing emergency response capabilities, the agency aims to safeguard communities and infrastructure downstream while maintaining the dam's vital flood protection function.
