Lake Shenandoah Dam

About Lake Shenandoah Dam

The primary purpose of Lake Shenandoah Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by County Of Ocean (local government). It impounds the South Branch Metedeconk River.

The dam stands 17 feet tall and stretches 375 feet across, creates a reservoir covering 45 acres, has a storage capacity of 111 acre-feet, and collects water from a drainage area of 29 square miles. Completed in 1934, the structure is well-established, with more than 75 years of service.

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 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 09/15/2023.
