About Hallquist Dam
The primary purpose of Hallquist 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 Hallquist (private). It impounds the Unnamed Trib to Tarkio R near Stanton.
