About Willow Creek Watershed Dam A- 23
The primary purpose of Willow Creek Watershed Dam A- 23 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 Willow Creek Wrsd Subdis (local government). It impounds the Tr-willow Creek near Henrietta.
The dam stands 34 feet tall and stretches 625 feet across, creates a reservoir covering 17 acres, has a maximum storage capacity of 138 acre-feet, and collects water from a drainage area of 231 square miles. Completed in 1970, the structure is well into its service life at over 50 years old.
