About Luetkemeyer Dam
The primary purpose of Luetkemeyer 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 David Luetkemeyer (private). It impounds the Tr-madden Branch near Joanna.
The dam stands 34 feet tall and stretches 600 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 81 acre-feet, and collects water from a drainage area of 422 square miles. Completed in 2007, the structure is relatively new.
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. The most recent inspection on record was 11/01/2007. That was over 18 years ago.
At 34 feet, this dam is taller than 78% of dams nationwide.
