About Harvey Dam
The primary purpose of Harvey 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 Curtis Harvey (private). It impounds the Trib to Wolf Creek near Lockridge.
The dam stands 26 feet tall and stretches 310 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 40 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2006, 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.
