Denny Pond Dam

About Denny Pond Dam

The primary purpose of Denny Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Dengar Inc (private). It impounds the Tr-lynches River.

The dam stands 12 feet tall, creates a reservoir covering 9 acres, and has a maximum storage capacity of 65 acre-feet. Completed in 1957, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 11/14/2023.
