Heywood Lake
Heywood Lake is an earth dam located in Adair County, Missouri, built in 1996. It carries a Low hazard potential classification.
About Heywood Lake
The primary purpose of Heywood Lake 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 Roy Heywood (private). It impounds the Tr-shuteye Creek near Stahl.
The dam stands 31 feet tall and stretches 340 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 20 acre-feet, and collects water from a drainage area of 38 square miles. Completed in 1996, the structure is 30 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.
