About Lake Hamilton
The primary purpose of Lake Hamilton is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Tompkins Realty & Development (private). It impounds the Factory Creek.
The dam stands 15 feet tall and stretches 370 feet across, creates a reservoir covering 30 acres, has a maximum storage capacity of 354 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1954, 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 11/23/2020.
