About Beinhart Dam
The primary purpose of Beinhart 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 Rodger and Molly Beinhart (private). It impounds the Tr to Dutch Cr near Coppock.
The dam stands 30 feet tall and stretches 325 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 26 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2023, 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.
