About Hughes Dam
The primary purpose of Hughes 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 Russell Hughes (private). It impounds the Trib To English Creek near New Sharon.
The dam stands 27 feet tall and stretches 395 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 46 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2010, 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.
