About Mckean Dam
The primary purpose of Mckean 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 John Mckean (private). It impounds the Trib To Kemp Creek near Nodaway.
The dam stands 29 feet tall and stretches 419 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 30 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2013, 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.
