Deer Head Lake Dam

About Deer Head Lake Dam

The primary purpose of Deer Head Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Township Of Lacey (local government). It impounds the North Branch Forked River near Forked River.

The dam stands 9 feet tall and stretches 660 feet across, creates a reservoir covering 92 acres, has a maximum storage capacity of 350 acre-feet, and collects water from a drainage area of 13 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 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 03/12/2025.
