About Lautner Dam
The primary purpose of Lautner 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 Phillip Lautner (private). It impounds the Trib to North Raccoon near Dawson.
The dam stands 35 feet tall and stretches 190 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 37 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2004, 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.
At 35 feet, this dam is taller than 80% of dams nationwide.
