About Elmwood No 77a
The primary purpose of Elmwood No 77a 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 Lee Reece (local government). It impounds the Tr-east Locust Creek near Milan.
The dam stands 31 feet tall and stretches 210 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 43 acre-feet, and collects water from a drainage area of 192 square miles. Completed in 1984, the structure is 42 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.
