Dinsmore No 2

About Dinsmore No 2

The primary purpose of Dinsmore No 2 is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Goodwill Hill Hunting And Fishing Club (private). It impounds the Harmon Creek.

The dam stands 27 feet tall and stretches 410 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 133 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1909, the structure is over a century 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 03/23/2021.
