About Forrest Coffelt Structure Dam

The primary purpose of Forrest Coffelt Structure 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 Forrest Coffelt (private). It impounds the Tr-nodaway River near Maitland.

The dam stands 26 feet tall and stretches 250 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 36 acre-feet, and collects water from a drainage area of 147 square miles. Completed in 1978, the structure is 48 years old.

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.
