The primary purpose of this concrete dam, completed in 1939, is for recreation, specifically for fish and wildlife pond activities. With a dam height of 27 feet and a storage capacity of 90 acre-feet, this reservoir covers a surface area of 7 acres and serves as a critical water source in the region.
Managed by the Forest Service, Granite Basin has a spillway width of 300 feet and a maximum discharge of 5300 cubic feet per second. Despite its high hazard potential, the dam's condition is not currently rated. The last inspection in August 2019 revealed a moderate risk level with no specific risk management measures identified. With its picturesque setting and recreational opportunities, Granite Basin is a key location for water resource and climate enthusiasts to explore and appreciate the importance of sustainable water management practices in the face of changing climate conditions.
