Oyler Lake Dam is an earth dam located in Ray County, Missouri, built in 1977. It carries a Significant hazard potential classification.
About Oyler Lake Dam
The primary purpose of Oyler Lake 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 Frank Oyler (private). It impounds the Tr-dangerous Br Crooked River near Hardin.
The dam stands 26 feet tall and stretches 450 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 34 acre-feet, and collects water from a drainage area of 493 square miles. Completed in 1977, the structure is 49 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life.
