About Barber Lake Dam No 1(sec 31)
The primary purpose of Barber Lake Dam No 1(sec 31) 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 Harry Barber (private). It impounds the Tr-tebo Creek near Calhoun.
The dam stands 21 feet tall and stretches 520 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 57 acre-feet, and collects water from a drainage area of 172 square miles. Completed in 1972, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life.
