Folsom Dike 2, located in Placer, California, is a vital flood risk reduction structure along the American River. Built in 1956 by the Bureau of Reclamation, this earth dam stands at a height of 15 feet and spans a length of 1800 feet. With a storage capacity of 1,120,000 acre-feet, it serves multiple purposes including flood risk reduction, hydroelectric power generation, irrigation, recreation, and water supply.

Managed by the Bureau of Reclamation, Folsom Dike 2 has a high hazard potential and is regularly inspected to ensure its structural integrity. Despite being classified as high-risk, the dam lacks an available condition assessment, emphasizing the need for continued monitoring and risk management measures. With a focus on flood risk reduction, the dam plays a crucial role in protecting the surrounding areas from potential inundation during periods of high water flow.

While Folsom Dike 2 does not have a spillway, its strategic location and design make it a key infrastructure for water resource management in the region. As climate change continues to impact water availability and extreme weather events, this dam remains a critical piece of infrastructure for mitigating flood risks and ensuring the safety and security of the surrounding communities along the American River.
