Bass Lake Dam

About Bass Lake Dam

The primary purpose of Bass Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Princeton Blairstown Center (private). It impounds the Blairs Creek near Blairstown.

The dam stands 30 feet tall and stretches 108 feet across, creates a reservoir covering 15 acres, has a maximum storage capacity of 325 acre-feet, and collects water from a drainage area of 5 square miles. 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 10/12/2023.
