White Rock Lake, located in California's Nevada County, is a private hydroelectric dam with a rich history dating back to 1855. The dam stands at 13.5 feet tall and has a capacity of 850 acre-feet, providing power through its earth dam structure on White Rock Creek. With a surface area of 90 acres and a drainage area of 1.2 square miles, the dam plays a crucial role in water resource management and climate resilience in the region.

Managed by the Federal Energy Regulatory Commission, White Rock Lake has a low hazard potential and a moderate risk assessment. Despite its age, the dam is regularly inspected and meets regulatory standards for state permitting, inspection, and enforcement. The dam's uncontrolled spillway and 40-foot spillway width ensure efficient water flow and safety measures in case of emergencies. With its location in the beautiful Hobart Hills and its vital role in hydroelectric power generation, White Rock Lake is a fascinating site for water resource and climate enthusiasts to explore and learn about the intersection of infrastructure and environmental stewardship.
