Omisol Dam

About Omisol Dam

The primary purpose of Omisol Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Omisol Homeowners Association (private). It impounds the Hooes Run.

The dam stands 21 feet tall and stretches 250 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 156 acre-feet, and collects water from a drainage area of 5 square miles.

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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 08/21/2012. That was 13 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
