Mill Pond Dam

About Mill Pond Dam

The primary purpose of Mill Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Park Ridge Borough (local government). It impounds the Pascak Brook near Park Ridge.

The dam stands 21 feet tall and stretches 588 feet across, creates a reservoir covering 7 acres, has a storage capacity of 22 acre-feet, and collects water from a drainage area of 14 square miles. Completed in 1908, 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 03/22/2024.
