About Tabo Creek Watershed Dam A-20
The primary purpose of Tabo Creek Watershed Dam A-20 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 Tabo Cr Wrsd Subdistrict (local government). It impounds the Tabo Creek near Norborne.
The dam stands 26 feet tall and stretches 385 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 60 acre-feet, and collects water from a drainage area of 80 square miles. Completed in 1963, 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.
