The Blackfoot River is a world-class trout fishing vacation spot that runs by western Montana. Made well-known in Norman Maclean’s A River Runs By It, the Blackfoot nonetheless attracts anglers from all around the world. However at the moment, it’s going through severe growth threats that might degrade water high quality and fish habitat for a few years to come back.
In April, a doable gold mine within the headwaters and an information heart on the river’s decrease stretches made headlines. Now, these threats are transferring nearer to turning into actuality. On June 8, the Montana Division of Environmental High quality (DEQ) authorised an exploratory allow for the Australian-owned Sentinel Metals. The license will enable Sentinel to drill core sampling holes as much as 14,359-feet deep within the Blackfoot’s headwaters.
Exploratory drilling isn’t anticipated to have an outsized impression on the fishery. However what comes subsequent definitely may. “The subsequent step will probably be a gold mine,” Large Blackfoot Riverkeeper Government Director Jerry O’Connell, who lives in a homestead on the banks of the river, tells Discipline and Stream. Given the vertical place of the gold vein, consultants say the likeliest methodology of mining it could be an open-pit mine. “It’d be a quarter-mile extensive, half-a-mile lengthy, and at the least 700-to-900 toes deep to start out,” O’Connell says.
David Brooks, Government Director of Montana Trout Limitless, says the one solution to make an open-pit mine worthwhile is to make use of cyanide-heap leaching to extract the gold. “Montanans handed a poll inititive that banned cyanide-heap leaching years in the past,” Brooks tells F&S. “Now, there’s the potential that they are going to look to overturn the ban. The corporate says they aren’t going to make use of an open pit or use cyanide, however the geo-technical proof says in any other case.”
One of many causes the proposed mine is so worrying has to do with the historical past of the river. In 1975, the Mike Horse Dam failed, flushing heavy-metal mine tailings all the way in which downstream. A decades-long, multi-million-dollar mitigation effort helped the river get well—solely to face further mining threats at the moment.
A New Mining Outfit Enters the Fray
Along with Sentinel, one other mining firm referred to as Mogotes Metals—a mineral exploration firm targeted on Argentina and Chile—not too long ago introduced renewed exploratory efforts below present permits within the “Copper Cliff Website” close to Potomac, Montana. Mining actions there may additionally threaten the water high quality of the Blackfoot River.
In keeping with Brooks, mining firms are eyeing spots alongside different well-known Montana trout rivers. Not removed from the Blackfoot, as an illustration, a proposed uncommon–earth mine on the headwaters of the Bitterroot River has additionally raised concern. “There’s an financial driver,” he says. “In 2026, gold costs have been over $5,000 twice, which is unprecedented. The costs for different metals are excessive, too. And Montana particularly has fairly mining-friendly legal guidelines.”
Brooks and O’Connell say that for the reason that mines proposed for the Blackfoot are nonetheless in exploratory phases, there’s not a lot that may be executed—for now. Court docket challenges are possible the greatest path to stopping them, even supposing the general public is overwhelmingly in opposition to the brand new mines.
“There’s no field to be checked within the state’s allowing course of for public opinion,” says Brooks. “The [Blackfoot] is a spot we’ve invested lots in to scrub up from previous mining and to deliver again this fishery. We ought to be actually cautious about new mines undoing all that funding.”
Knowledge Heart Looms, Too
One other menace to the Blackfoot River is the event of an information heart in Bonner, Montana, alongside the bottom-most section of the river. In keeping with Missoula County, the proposed information heart in Bonner, backed by Idaho-based Krambu, would function 24-hours a day, seven days per week and use roughly 7 megawatts of electrical energy to start out, earlier than doubtlessly ramping as much as 29 megawatts. Krambu is presently finalizing its supplies to be offered to the Missoula Consolidated Land Use Board.
The required infrastructure to produce electrical energy at this stage, in addition to the water-use of the proposed AI information heart, and the impression of noise on the group and the river hall, have locals alarmed. “Krambu says they’re going to make use of a closed-loop cooling system,” says O’Connell. “That’s bull. The water goes to come back out of the water desk, and the river and the water desk are related. It’s going to have an effect on the Blackfoot and the Clark Fork River. It’s only a dangerous place to place an information heart.”
Brooks shares O’Connell’s worries. “There must be rather more clear details about water and habitat impacts,” he says. “There additionally must be extra information in regards to the different infrastructure that the information heart would necessitate, which may additionally impression the well being of the river.”
Over the previous few weeks, a number of grassroots organizations, corresponding to Missoula Neighbors United and the No Bonner Knowledge Heart Instagram web page, have organized public group discussions. Overwhelming public sentiment reveals grave concern in regards to the potential impacts of the information heart to the Blackfoot itself and the favored recreation hall that surrounds the river.
On June 12, Missoula County introduced that its workers had reviewed one other software submitted by Krambu however that it was thought of “inadequate” for overview by the Missoula Consolidated Land Use Board. The corporate is predicted to revise and resubmit its proposal.

The threats come as drought situations and low flows have additionally taken a toll on the river and its fish. “The Blackfoot is in danger,” says O’Connell. “However the good factor is we’re getting publicity for these dangers. And there’s curiosity from folks, not simply round right here however worldwide, as a result of the Blackfoot is particular. It’s one thing particular.”
