About Duncan Dam
The primary purpose of Duncan 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 Fred Duncan (private). It impounds the Tr-locust Creek near Sumner.
The dam stands 32 feet tall and stretches 270 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 22 acre-feet, and collects water from a drainage area of 256 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 20 years ago.
At 32 feet, this dam is taller than 76% of dams nationwide.
