About Marlay Dam
The primary purpose of Marlay 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 Lyle Marlay (private). It impounds the Tr- Fox River near Mount Sterling.
The dam stands 27 feet tall and stretches 350 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 121 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1999, the structure is 27 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.
