The Blackfoot River flows 130 miles from its headwaters near the Continental Divide west through broad valleys and deep ponderosa-lined canyons before joining the Clark Fork River just east of Missoula. Norman Maclean immortalized this river in "A River Runs Through It," and the Blackfoot has since become one of the most culturally significant fly fishing rivers in the world — a river that introduced generations of anglers to the art and ethos of the sport. The restoration of the Blackfoot following decades of mining impacts and dewatering is one of the great conservation success stories in western fly fishing, led by the Blackfoot Challenge collaborative beginning in the 1990s. Today the river holds healthy populations of wild Westslope cutthroat, rainbow, and brown trout, with the native cutthroat making a particularly strong recovery. Bull trout are present throughout the system — protected, catch and release only, and any encounter should be reported to Montana FWP.
The Blackfoot River Salmonfly hatch is among the most prolific and longest-lasting in all of Montana. While most Montana rivers compress the Salmonfly window to 10-14 days, the Blackfoot's hatch typically begins around the second week of June and lasts well past the Fourth of July in most years — an extraordinary duration that gives anglers far more opportunity to hit the hatch than on neighboring rivers. The hatch progresses upstream as water temperatures warm through the canyon, with the lower river going first and the upper sections firing weeks later. Giant foam flies, Chernobyl Ants, and Super Gee patterns in sizes 4-6 are the standard imitations. A 6 or 7 weight rod handles the big flies and applies pressure needed in the strong current when a large brown or cutthroat takes on the surface.
The Spruce Moth hatch in August is a uniquely Blackfoot River phenomenon that causes some of the most aggressive and reckless dry fly feeding of the year. As the common name suggests, Spruce Moth adults fall from the ponderosa pine forests lining the canyon banks in significant numbers through August, and large trout that have become selective and cautious through the summer months suddenly abandon caution to eat these terrestrials from the surface. Elk Hair Caddis and Spruce Moth patterns in sizes 12-14 are the standard imitations. This is one of the better opportunities to catch large fish on dry flies during a period when most Montana rivers are fishing poorly in the afternoon heat.
Montana Fish, Wildlife and Parks imposes Hoot Owl fishing restrictions on the Blackfoot River when water temperatures exceed 73°F — typically from mid-July through late August in warm years. Under restrictions, fishing is prohibited from 2pm to midnight. Early morning from first light to 2pm is the productive window. Always check current FWP restriction status at fwp.mt.gov before heading to the water — restrictions can be lifted as quickly as they are imposed when temperatures drop after cool nights or rain events. Voluntarily practicing early morning fishing and releasing fish quickly during warm weather even without formal restrictions protects the wild trout populations that make the Blackfoot worth fishing.
The recovery of the Blackfoot River is a model for collaborative watershed conservation. Mining contamination from historical operations, irrigation dewatering, and habitat degradation had significantly impacted the fishery by the late 20th century. The Blackfoot Challenge — a coalition of landowners, conservation groups, agencies, and businesses — has worked since the 1990s to restore streamflows, improve water quality, restore riparian habitat, and reintroduce native species. Westslope cutthroat trout populations have recovered substantially and the river's bull trout population, though still fragile, continues to improve. Anglers fishing the Blackfoot are benefiting from decades of this conservation work and supporting it through license fees and TU membership.
