Cottonwood-Baggs Fish Passage

In the late fall of 2019, the Coalition finished a stream reconnection project on Baggs Creek and Cottonwood Creek in the upper Clark Fork. Eight miles of stream was opened to fish passage for the first time in many decades. Cottonwood Creek also benefited from a large fish screen project…
Valiton Ditch Split Season Lease

Three landowners are working with us to reduce late season water use on the mainstem Clark Fork. They lease CFC their water right from mid-July through August and cease irrigation if flows reach low levels. We also improved a diversion to help fish passage. This project strikes a balance between…
Broken Circle Diversion Upgrade

Historically, Broken Circle Ranch rebuilt their irrigation diversion every summer using broken concrete and streambed material, which resulted in passage issues for fish and recreationists. In 2023, the ranch worked with the Coalition to install an innovative floating fish screen and river pump that requires minimal structure in the river…
Community Science Monitoring Miller Creek

On Miller Creek, community science volunteers assessed habitat, noxious weeds, and riparian vegetation species diversity pre- and post stream restoration at two sites. Community science is scientific work undertaken by members of the public in collaboration with professional scientists and scientific institutions. When community members and scientists work together, scientists are…
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
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.
