About Wagner Dam
The primary purpose of Wagner 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 Robert D Wagner (private). It impounds the Tr- North English River near Guernsey.
The dam stands 29 feet tall and stretches 410 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 81 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2001, 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.
