Lake Tiaroga Dam

About Lake Tiaroga Dam

The primary purpose of Lake Tiaroga Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Connestee Falls Poa, Inc. (private). It impounds the Batson Creek near Dunns Rock.

The dam stands 47 feet tall and stretches 261 feet across, creates a reservoir covering 32 acres, and has a maximum storage capacity of 1,010 acre-feet.

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 04/25/2025.

At 47 feet, this dam is taller than 92% of dams nationwide.
