Old Keyser Reservoir

About Old Keyser Reservoir

Old Keyser Reservoir is a dam in Mineral, West Virginia. The dam is owned by City Of Keyser (local government). It impounds the Limestone Run near Water Supply.

The dam stands 25 feet tall and stretches 332 feet across, creates a reservoir covering 5 acres, and has a maximum storage capacity of 62 acre-feet. Completed in 1911, 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 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 08/20/2012. That was 13 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
