About Seyb Dam
The primary purpose of Seyb 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 George Seyb (private). It impounds the Little Fox River near Ashton.
The dam stands 34 feet tall and stretches 235 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 40 acre-feet, and collects water from a drainage area of 190 square miles. Completed in 1995, the structure is 31 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.
At 34 feet, this dam is taller than 80% of dams nationwide.
