Coalburg Lake Dam

About Coalburg Lake Dam

The primary purpose of Coalburg Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Coalburg Land Partners, Llc (private). It impounds the Little Yankee Run near Coalburg.

The dam stands 24 feet tall and stretches 600 feet across, creates a reservoir covering 57 acres, has a maximum storage capacity of 770 acre-feet, and collects water from a drainage area of 14 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 11/21/2019.
