About Mather Dam

The primary purpose of Mather 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 Lewis Mather & Sons (private). It impounds the Trib To Tarkio Cr near Blanchard.

The dam stands 33 feet tall and stretches 614 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 60 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2012, 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.

At 33 feet, this dam is taller than 78% of dams nationwide.
