About Willow Creek Watershed Dam A- 27

The primary purpose of Willow Creek Watershed Dam A- 27 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 Cr Wrsd Subdistrt (local government). It impounds the Tr-willow Creek near Henrietta.

The dam stands 35 feet tall and stretches 650 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 268 acre-feet, and collects water from a drainage area of 380 square miles. Completed in 1972, the structure is well into its service life at over 50 years old.

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 05/17/1979. That was over 46 years ago.

At 35 feet, this dam is taller than 82% of dams nationwide.
