About Ferguson #1 Dam
The primary purpose of Ferguson #1 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 John Ferguson (private). It impounds the Tr-little Blue River near Atherton.
The dam stands 30 feet tall and stretches 425 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 32 acre-feet, and collects water from a drainage area of 236 square miles. Completed in 1994, the structure is 32 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.
