About Dredge Dam

The primary purpose of Dredge Dam is grade stabilization. Grade stabilization dams prevent erosion by reducing the slope and velocity of water flowing through a channel. They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Clinton Dredge (private). It impounds the Trib To Walnut Creek near Delphos.

The dam stands 26 feet tall and stretches 489 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 93 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2013, the structure is relatively new.

This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
