Changing the Status of Sediment

Oregon Creek is a headwater tributary that feeds into the Big Hole River and is approximately 12 miles southeast of Anaconda in the Mount Haggin Wildlife Management Area. It extends downstream from the Highway 569 crossing to the confluence with California Creek.

Oregon Creek is listed on DEQ’s List of Impaired Waters for lead, arsenic, copper, sedimentation/siltation, alteration in streamside or lateral vegetative covers, physical habitat substrate alterations, and other anthropogenic substrate alterations and physical substrate habitat alterations. Montana Fish, Wildlife and Parks (FWP) identified the project’s reach for restoration due to the continued degradation of wetland and riparian functions as well as other habitat impairments.
