Cranberry Lake Dam

About Cranberry Lake Dam

The primary purpose of Cranberry Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Division Of Parks And Forestry (state). It impounds the Lubbers Run.

The dam stands 18 feet tall and stretches 1,000 feet across, creates a reservoir covering 191 acres, has a storage capacity of 2,457 acre-feet, and collects water from a drainage area of 3 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 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 08/29/2024.
