About Lake Milton Dam

The primary purpose of Lake Milton Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Odnr, Division Of Parks & Watercraft (state). It impounds the Mahoning River near Newton Falls.

The dam stands 53 feet tall and stretches 2,840 feet across, creates a reservoir covering 1,780 acres, has a maximum storage capacity of 46,605 acre-feet, and collects water from a drainage area of 276 square miles. Completed in 1916, 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 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 04/20/2016. 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.
