About Magruder Dam
The primary purpose of Magruder 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 Richard Magruder (private). It impounds the Crooked Creek near Lenter.
The dam stands 22 feet tall and stretches 813 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 73 acre-feet, and collects water from a drainage area of 473 square miles. Completed in 1995, the structure is 31 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.
