About Goddard Dam
The primary purpose of Goddard 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 Randy Goddard (private). It impounds the Unnamed Tributary To The Little Tarkio Creek near Stanton.
The dam stands 25 feet tall and stretches 550 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 95 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2023, 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.
