About French Landing

The primary purpose of French Landing is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. It impounds the Huron River near New Boston.

The dam stands 38 feet tall and stretches 890 feet across, creates a reservoir covering 1,270 acres, has a maximum storage capacity of 18,000 acre-feet, and collects water from a drainage area of 833 square miles. Completed in 1924, 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 08/03/2022.

At 38 feet, this dam is taller than 85% of dams nationwide.
