About Rigdon Dam
The primary purpose of Rigdon 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 Charles Rigton (private). It impounds the Tr-brush Creek near Greentop.
The dam stands 33 feet tall and stretches 308 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 22 acre-feet, and collects water from a drainage area of 335 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.
At 33 feet, this dam is taller than 76% of dams nationwide.
