Hammonton Lake Dam

About Hammonton Lake Dam

The primary purpose of Hammonton Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Njdot (state). It impounds the Hammonton Creek near Wescoatwille.

The dam stands 13 feet tall and stretches 325 feet across, creates a reservoir covering 71 acres, has a storage capacity of 426 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1902, the structure is over a century old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. 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 08/01/2023.
