About Mccreary Dam
The primary purpose of Mccreary 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 Marvin Mccreary (private). It impounds the To Unionville Reservoir near Unionville.
The dam stands 28 feet tall and stretches 341 feet across, creates a reservoir covering 25 acres, has a maximum storage capacity of 29 acre-feet, and collects water from a drainage area of 1,845 square miles. Completed in 1994, the structure is 32 years old.
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.
