About Stump Pond Dam

The primary purpose of Stump Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Charles Sudbrink (private). It impounds the Willet Creek near Willet.

The dam stands 15 feet tall and stretches 100 feet across, creates a reservoir covering 39 acres, has a maximum storage capacity of 347 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1928, the structure is well-established, with more than 75 years of service.

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.
