Green Dam
Green Dam is an earth dam located in Scotland County, Missouri, built in 1991. It carries a Low hazard potential classification.
About Green Dam
The primary purpose of Green 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 Charles B. Green (private). It impounds the Tr-middle Fabius River near Hannibal.
The dam stands 27 feet tall and stretches 313 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 47 acre-feet, and collects water from a drainage area of 115 square miles. Completed in 1991, the structure is 35 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.
