About Treesdale Impoundment #1

The primary purpose of Treesdale Impoundment #1 is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Treesdale Country Club Inc (private). It impounds the Tr Breakneck Creek.

The dam stands 15 feet tall and stretches 320 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 82 acre-feet, and collects water from a drainage area of 1 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 09/16/2020.
