About Foxwood Lake Dam
The primary purpose of Foxwood Lake Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Allen County Drainage Board (private). It impounds the Tiernan Ditch.
The dam stands 10 feet tall and stretches 400 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 140 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2006, the structure is relatively new.
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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 09/17/2020.
