About Steinbeck/iowa DNR
The primary purpose of Steinbeck/iowa DNR 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 Iowa Department of Natural Resources (state). It impounds the Tr-honey Creek near Coppock.
The dam stands 27 feet tall and stretches 385 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 112 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2003, 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.
