About Andrews Dam
The primary purpose of Andrews 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 Kevin Andrews (private). It impounds the Tr-fox River near Kahoka.
The dam stands 29 feet tall and stretches 280 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 19 acre-feet, and collects water from a drainage area of 384 square miles. Completed in 2005, 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. The most recent inspection on record was 09/30/2005. That was over 21 years ago.
