Three Mile Creek - Sediment Reduction


Three Mile Road outside of Stevensville, MT


Reduce the amount of fine sediment entering (polluting) the creek from the road at the road/creek crossing.


Three Mile Road is a frequently used road system that is right next to Three Mile Creek. Dirt roads bordering creeks can cause pollution when they contribute excess eroded sediment (fine debris) into the waterway. Threemile Creek is a significant contributor of contaminated, over-sedimented water to the Bitterroot River which decreases clarity and degrades fish habitat.

Project Description

  • The Ravalli County Road and Bridge Department installed a culvert and applied crushed rock to armor the surface of the road.

  • The Water Forum will monitor the effectiveness of the project to reduce sediment delivery
