About Beaver Glenn Lake Dam
The primary purpose of Beaver Glenn Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Warren (private). It impounds the Trib East Bureau Creek near Coal Hollow.
The dam stands 24 feet tall and stretches 340 feet across, creates a reservoir covering 15 acres, has a maximum storage capacity of 254 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1973, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 07/18/2025.
