About Heck Dam
The primary purpose of Heck 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 Virgil Heck (private). It impounds the Tr-middle Branch Squaw Ck near Mound City.
The dam stands 31 feet tall and stretches 580 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 42 acre-feet, and collects water from a drainage area of 32 square miles. Completed in 1989, the structure is 37 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.
