Manistique Papers Dam

About Manistique Papers Dam

The primary purpose of Manistique Papers Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Manistique Paper, Inc. (private). It impounds the Manistique River near Manistique.

The dam stands 25 feet tall and stretches 6,180 feet across, creates a reservoir covering 480 acres, has a maximum storage capacity of 6,000 acre-feet, and collects water from a drainage area of 1,450 square miles. Completed in 1919, 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 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 04/27/2016. That was 9 years ago, which is on the longer end for a high-hazard structure.
