About Peterson Dam #2
The primary purpose of Peterson Dam #2 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 Leon Peterson (private). It impounds the Trib to Phillips Creek near Winfield.
The dam stands 27 feet tall and stretches 615 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 170 acre-feet, and collects water from a drainage area of 0 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.
