About Mineral Ridge Dam
The primary purpose of Mineral Ridge Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Mahoning Valley Sanitary District (local government). It impounds the Meander Creek near Evansville.
The dam stands 60 feet tall and stretches 3,480 feet across, creates a reservoir covering 2,109 acres, has a maximum storage capacity of 62,000 acre-feet, and collects water from a drainage area of 83 square miles. Completed in 1932, 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. The most recent inspection on record was 07/08/2021.
At 60 feet, this dam is taller than 95% of all dams in the United States.
