About Soap Creek Watershed Site 26-55

The primary purpose of Soap Creek Watershed Site 26-55 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 Davis County Swcd (local government). It impounds the Coon Creek near Eldon.

The dam stands 40 feet tall and stretches 1,000 feet across, creates a reservoir covering 20 acres, has a maximum storage capacity of 883 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 2007, 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.

At 40 feet, this dam is taller than 87% of dams nationwide.
