About Gerot Dam
The primary purpose of Gerot 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 Dean Gerot (private). It impounds the Tr- Iowa River near Columbus Junction.
The dam stands 28 feet tall and stretches 210 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 22 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1999, the structure is 27 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.
