About James A.waters Lake Dam
The primary purpose of James A.waters Lake 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 James A.waters (private). It impounds the Tr-wakenda Creek near Carrollton.
The dam stands 21 feet tall and stretches 400 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 73 acre-feet, and collects water from a drainage area of 134 square miles. Completed in 1974, 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.
