Tanner Lake Dam
Tanner Lake Dam is an earth dam located in Ray County, Missouri, built in 1975. It carries a Significant hazard potential classification.
About Tanner Lake Dam
The primary purpose of Tanner 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 Oswald Tanner (private). It impounds the Tr-cravens Creek near Camden.
The dam stands 30 feet tall and stretches 700 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 108 acre-feet, and collects water from a drainage area of 278 square miles. Completed in 1975, the structure is well into its service life at over 50 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. The most recent inspection on record was 07/02/1980. That was over 45 years ago.
