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…
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.

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.
