Columbia Gold Mine Exploration Project

Background With prices of gold at an all-time high, many mining projects that were previously shelved are receiving renewed interest. This includes a potential gold mine project that could present a very real threat to the Blackfoot…
Sheep Creek Mine Proposal

Background We’ve been tracking the proposed Sheep Creek Mine project – located in the headwaters of the West Fork of the Bitterroot River — since its inception, and we were among the roughly 500 concerned citizens and conservation groups that joined an emergency hearing in front of the Ravalli County Commissioners in December…
Exempt Wells

Background In 1973, the Montana Legislature passed the Water Use Act, which created a process for permitting new water rights. To reduce permitting burdens on small, individual users, it exempted groundwater use for “domestic, agricultural, or livestock purposes.” This meant applicants did not have to prove that the water was…
Sager Lane Pin & Plank Diversion Removal

Restoring Flow and Fish Passage at Sager Lane In September 2024, we began work to remove a century-old “pin and plank” irrigation…
Mike Horse Mine Cleanup

In the 1940s, miners used metals-laced tailings to build the Mike Horse Dam at the origins of the Blackfoot River on Beartrap Creek near the Continental Divide. In 1975, the tailings dam blew out, dumping deadly levels of lead, copper and zinc into the Blackfoot. The mine’s corporate owner, ASARCO, rebuilt…
Protecting Selenium Standards in Lake Koocanusa

Background: Lake Koocanusa is a long, narrow 90-mile reservoir created by the Libby Dam in Northwestern Montana. It’s headwaters and mountainous shoreline reach across the border into British Columbia, Canada where the Kootenay, Bull, and Elk rivers feed into the lake. Id. The reservoir’s snow-fed waters support diverse aquatic species, including burbot,…
Dry Cottonwood Creek Ranch

Cattle and Clean Water at Dry Cottonwood Creek Ranch From 2005 to 2021, Clark Fork Coalition and partners ran Dry Cottonwood Creek Ranch (DCCR), a 2,300-acre working cattle ranch in Montana’s Deer Lodge Valley, to be a living classroom for the largest river repair job in the West, located in…
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…
Valiton Ditch Split Season Lease

In summer 2024, after years of work toward a diversion reduction agreement and a 20-year split-season water lease agreement with local landowners, we successfully decommissioned the Valiton Ditch and legally protected 13 cfs of new instream flow water in the Clark Fork River which would have been previously diverted into…
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…
Helen-Johnson Ditch Project

The Helen Johnson project reduced irrigation withdrawals from the mainstem of the Upper Clark Fork by over 15 cfs on three ranches. It removed a…
Community Science Monitoring

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…
