Olson Dam
Olson Dam is an earth dam located in Monroe County, Missouri, built in 1994. It carries a Low hazard potential classification.
About Olson Dam
The primary purpose of Olson 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 Gloria English Olson (private). It impounds the Pooles Branch near Paris.
The dam stands 25 feet tall and stretches 580 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 64 acre-feet, and collects water from a drainage area of 121 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.
