About Glenn Lake Dam
The primary purpose of 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 United Minerals (private). It impounds the Duck Branch near Chatsworth.
The dam stands 53 feet tall and stretches 255 feet across, creates a reservoir covering 4 acres, and has a maximum storage capacity of 80 acre-feet. Completed in 1951, 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. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 03/09/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.
At 53 feet, this dam is taller than 94% of dams nationwide.
