Cabinet Mountain Mines and Bad Actors

The Cabinet Mountains Wilderness provides refuge for native fish and wildlife and its streams flow with some of the purest waters in the lower 48. It also contains one of the largest copper/silver deposits in the world. We work with our partners Earthworks, Earthjustice, Rock Creek Alliance, and Montana Environmental…
Thermal Mapping of the Upper Clark

Professor Raja Nagisetty and environmental engineering graduate student Meggie Olsen at Montana Tech, along with several other collaborators, completed a series of drone flights on the upper Clark Fork River to study thermal refugia habitat. Professor Raja and his team documented an unremediated reach of the Upper Clark Fork…
Assessments of Geomorphology and Macroinvertebrate Diversity

The CFC has coordinated data collection efforts with Professor Rob Thomas at UM Western annually since 2019. Over that period, Rob’s students have focused on a variety of studies in the UCF OU from assessments of geomorphology and macroinvertebrate diversity on both remediated and unremedied phases, to a study examining…
Slickens Assessments in the Upper Clark Fork

The CFC coordinated with Fish, Wildlife & Parks to complete a hazard assessment of the remaining slickens in Reach A of the Upper Clark Fork Superfund Operable Unit. In the summer of 2019, over 170 individual slickens were assessed and mapped for hazards related to surface runoff and channel avulsion…
Stonewall Creek

We permanently acquired 5 cfs of water rights that reconnect Stonewall Creek to the Blackfoot River year round. The creek supports native westslope cutthroat and brown trout.
Keep Cool Creek

We permanently acquired 5 cfs of water rights that reconnect Keep Cool Creek to the Blackfoot River year round.
West Fork Lee Creek Road Decommissioning and Fish Passage
East Fork Lolo Creek Restoration

On the East Fork Lolo Creek, we installed wood jams into the stream to create complex aquatic habitat and help filter and trap sediment. We also re-naturalized unused forest roads to decrease sources of sediment washing into the stream. Clark Fork Coalition has worked in the Upper Lolo watershed since…
Lost Horse Creek Monitoring

Gives us data on flow and temperature. We use flow data to determine when to close irrigation ditches and save water for stream function.
Lolo Ditch Fish Screen

In 2020, CFC completed installation of a fish screen on Lolo Ditch, which, before this project, had trapped 10,000 fish each year, greatly impacting native and wild fish populations.
Milltown Dam Removal

For 100 years, Milltown Dam blocked the confluence of the Clark Fork and Blackfoot rivers near Missoula, trapping toxic sediments that washed down from mines in Butte and contaminating local drinking water wells. Now, the dam is out, the mining waste is gone, fish can swim back upstream, and two mighty…
