About Karl Hamner Dam
The primary purpose of Karl Hamner 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 Karl Hamner (private). It impounds the Tr-wyaconda River near Darrahs.
The dam stands 29 feet tall and stretches 390 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 38 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2018, 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 05/21/2018.
