About Kevin Briggs Dam
The primary purpose of Kevin Briggs 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 Kevin Briggs (private). It impounds the Goodwater Creek near Lake Rathbun.
The dam stands 26 feet tall and stretches 390 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 39 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2019, the structure is relatively new.
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.
