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…
In-stream Sediment Sampling 2022

In partnership with Fish, Wildlife & Parks, Natural Resources Damage Program, and the University of Montana – Western, we measured the amount of sediment in streams along several reaches of the Upper Clark Fork River. Students collected over 70 in-stream sediment samples to see if sediment levels affect trout…
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…
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.
Poorman Creek

We permanently acquired 18 cfs of water rights that reconnect Poorman Creek to the Blackfoot River year round.
West Fork Lee Creek Road Decommissioning and Fish Passage
Granite Creek Restoration

To improve fish passage and reduce chronic stream sedimentation, we upgraded eight undersized culverts along Granite Creek Road. We also installed wood jams in the creek and reclaimed more than ten miles of unneeded forest roads. These projects decrease sedimentation, improve habitat connectivity, and increase the number of fish living…
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…
