About Gray Dam
The primary purpose of Gray 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 Nick Gray (private). It impounds the Tr_wolf Run near Clarinda.
The dam stands 30 feet tall and stretches 404 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 31 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2021, 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.
