Folsom Dike 6 is a vital structure located in Folsom, California, along the American River, constructed in 1956 by the Bureau of Reclamation for flood risk reduction. This Federal-owned earth dam stands at a height of 40 feet, with a hydraulic height of 35 feet and a structural height of 40 feet, serving multiple purposes including hydroelectric, irrigation, recreation, and water supply. With a storage capacity of 1.12 million acre-feet and a surface area of 11,180 acres, Folsom Dike 6 plays a crucial role in managing water resources in the region.

The dam, part of a larger system of 11 associated structures, has a high hazard potential due to its location and purpose. Although the condition assessment and risk management measures are not currently available, the Bureau of Reclamation oversees inspections and operations to ensure its integrity. Despite not having a spillway, the dam has never experienced a maximum discharge event. The emergency action plan was last revised in January 2020, aligning with guidelines and reflecting the high risk associated with the structure.

Folsom Dike 6's importance in flood risk reduction and water management cannot be understated, especially in the context of climate change and increasing water variability. As a key component of the water infrastructure in Placer County, California, this earth dam serves as a testament to the ongoing efforts to balance water supply, flood protection, and environmental sustainability. With a rich history dating back to its completion in 1956, Folsom Dike 6 continues to play a crucial role in safeguarding communities and ecosystems along the American River.
