Farmington Dam in San Joaquin, California, stands as a crucial Federal structure managed by the US Army Corps of Engineers for flood risk reduction, hydroelectric power generation, irrigation, and water supply. Completed in 1951, this earth dam with stone core spans 7,800 feet in length and stands 58 feet tall, holding a maximum storage capacity of 119,314 acre-feet. Despite its high hazard potential, the dam is well-equipped with an uncontrolled spillway and emergency action plan to mitigate risks associated with extreme weather events such as heavy rainfall, snow melting, and earthquakes that could potentially lead to downstream flooding of communities like Farmington and Stockton.

USACE's risk management efforts at Farmington Dam include regular inspections, instrument monitoring, and collaboration with local emergency managers to update emergency action plans and conduct drills. By incorporating weather forecasts and adjusting dam releases accordingly, USACE aims to minimize risks to downstream communities. In the event of a catastrophic scenario like an extreme earthquake or uncontrolled water surge, the emergency action plan is designed to lower the risk of life loss by providing timely warnings to residents. While such events are considered unlikely, USACE's proactive measures help ensure the safety and security of the surrounding area.
