Neer Dam
Neer Dam is an earth dam located in Lewis County, Missouri, built in 1994. It carries a Low hazard potential classification.
About Neer Dam
The primary purpose of Neer 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 Ron Neer (private). It impounds the Tr-oyster Creek near Lagrange.
The dam stands 30 feet tall and stretches 343 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 21 acre-feet, and collects water from a drainage area of 120 square miles. Completed in 1994, the structure is 32 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.
