About Wenger Dam
The primary purpose of Wenger 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 Myrna Wenger (private). It impounds the Trib To Crooked Creek near Coppock.
The dam stands 35 feet tall and stretches 180 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 20 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2005, 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.
At 35 feet, this dam is taller than 82% of dams nationwide.
