About Anderson Dam

The primary purpose of Anderson 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 Daniel S Anderson (private). It impounds the Tr- Tarkio River near Coin.

The dam stands 24 feet tall and stretches 532 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 70 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2000, the structure is 26 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.
