About Dwight Milligan Sr Dam
The primary purpose of Dwight Milligan Sr 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 Dwight Milligan Sr (private). It impounds the Tr-t Brush near Cainsville.
The dam stands 30 feet tall and stretches 266 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 19 acre-feet, and collects water from a drainage area of 74 square miles. Completed in 2002, 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. The most recent inspection on record was 11/21/2002. That was over 23 years ago.
