May 1, 2024
Bolan Lake Dam, located in Josephine County, Oregon, is a concrete gravity dam primarily used for fish and wildlife pond purposes. Built in 1972 by the Oregon State Game Commission, this Federal-owned structure on Bolan Creek stands at a height of 12 feet with a storage capacity of 165 acre-feet. The dam is managed and operated by the Forest Service and has a low hazard potential, with a moderate risk assessment rating.
The dam's design features a multi-arch core supported by rock and soil foundations, with an uncontrolled spillway width of 10 feet. The structure has not been rated for its condition but undergoes inspection every 10 years, with the last assessment conducted in May 2018. Despite its relatively small surface area of 50 acres and limited drainage area, Bolan Lake Dam serves as an important recreational spot in Cave Junction, Oregon, attracting water resource and climate enthusiasts to enjoy the tranquil surroundings and diverse wildlife supported by the pond.
With its focus on enhancing fish and wildlife habitat, Bolan Lake Dam serves as a valuable resource for both conservation and recreation in the region. As it continues to be managed by the Forest Service and monitored for safety and operational effectiveness, the dam remains a key feature in the local ecosystem, offering a unique opportunity for visitors to connect with nature and appreciate the intersection of water resource management and environmental stewardship.
