Southwest Montana rivers splitting—Madison and Gallatin stable and clear, but Big Hole and western drainages rising fast from snowmelt.

Madison and Missouri hold steady while Big Hole surges 17%. Southwest storm changes conditions through weekend—here's your fishing strategy.

Western Montana rivers climbing fast with incoming storm. Madison stable at 329 cfs. Wind gusts to 72 mph today—here's where to fish.

Southwest Montana rivers are holding steady and fishing well, but Western Montana is already surging—up 13–14% this week on the Clark Fork, Bitterroot, and Blackfoot as snowmelt kicks in. With a major Thursday–Friday weather system on the way, here’s a clear, river-by-river breakdown of flows, trends, and the best windows to fish before conditions change.

Early spring trout fishing near Bozeman is improving week by week as rivers transition out of winter mode. Here’s what’s working right now—best time of day, where trout are holding, and the nymph and streamer setups producing on the Gallatin, Madison (upper/lower), and Yellowstone as of March 9, 2026 (5/5).

March on Montana’s Missouri River is rarely predictable—and 2026 could be even more of a wildcard with low snowpack and warming water. Here’s what to expect for midges, nymphing, streamer fishing, swinging flies, and the fickle spring weather that can make (or break) your day on the Mo.

A short cold snap tightened the ice on Rock Creek just enough for Don Wilkins to get back out on Fort Peck and pick up several lake trout on jigs and plastics in 65–80 feet—while warning that a warm front could quickly end safe ice. Here’s the latest report, plus safety reminders before you go.

With the Gallatin running at 301 CFS at Gallatin Gateway, The River’s Edge reports fishing has been phenomenal—and even a colder stretch shouldn’t slow the bite much. Most consistent action is still subsurface: nymph rigs through deeper seams and buckets, or covering water with streamers. Here’s what’s working, plus section-by-section tips for fishing the Gallatin from Yellowstone to the Valley.

Spring breakup is underway at Tongue River Reservoir, with open water at both ramps and a few boats already out. But ice still blocks key stretches near the dam, between Sand Point and Pee Wee north, and at the far south end—limiting where you can safely travel right now. Here’s the latest access and ice update based on a recent FWP post.

Idaho Fish and Game’s March 3, 2026 Upper Salmon River steelhead report shows another strong week, with the best catch rates upstream of the Pahsimeroi (location codes 18–19). Midweek weather reduced clarity downstream, but conditions improved by the weekend and PIT tag detections at the Elevenmile (USE) array climbed to 136 for the run year.

Winter still has a say, but the Livingston-area bite improves steadily through mid-March—especially for bigger pre-spawn rainbows. Focus on afternoons (possibly late morning by March 1), fish low-and-slow in deep walking-pace pools, and watch for brief midge or winter BWO activity on warm, calm days. Here’s the latest river-by-river guidance from Yellowstone Country Fly Fishing.

Winter isn’t letting go yet—Whitefish Lake remains locked up with lake trout cruising deep structure, while the Flathead River rewards anglers who time it right. Here’s what’s producing now, from white tubes tipped with cutbait on the ice to nymphs and streamers in late-winter river water.

Grizzly Hackle’s boots-on-the-ground Bitterroot River report for Feb. 25, 2026: clear, stable flows; trout holding deep; nymphing still king with heavy stones, worms, and flashy perdigons. Expect afternoon midges on warmer days, selective dry-fly opportunities in flat water, and streamer eats on natural colors. Plus: spring-hatch countdown and a floaters-beware heads-up for downed trees.

From Chancy’s Fish Camp in Evergreen, MT: ice conditions are a mixed bag across NW Montana—some lakes still have decent ice, others are getting questionable, and a few are leaning into “boat season” vibes. Here’s what to watch for (including pressure ridges) and what anglers are targeting: perch, salmon through the ice, plus trolling for lake trout and rainbow trout.

With questions swirling from anglers, Don Wilkins went out to verify current ice conditions near the Fort Peck Dam. He checked the main channel and surrounding areas firsthand to give a clearer picture of what’s out there right now.

A mild winter kept the Upper Salmon River more open than usual in mid-February, with warmer water, a shorter ice jam, and stable flows. Monitoring from Feb. 11–15, 2026 also showed steelhead moving farther upstream than typical, with strong angler effort and good catch rates across most monitored areas.

February on Montana’s Missouri River is quiet, cold, and—when weather cooperates—surprisingly productive. With snowpack running roughly 80–90% of average, steady flows, and that key 36°F water-temp line dictating fish behavior, expect midges, deep-bucket nymphing, a sneaky-good winter streamer bite, and Trout Spey anglers swinging heavier tips through prime holding water. Here’s the latest Craig, MT update from Headhunters Fly Shop, plus what to watch as we inch toward spring and the 2026 guide season.

Winter fishing on the Jefferson River is challenging due to low trout densities. Patience with nymphing is necessary, but better fishing opportunities usually arise in early spring.

This winter fishing report for Southwest Montana details favorable conditions with mild temperatures, calm winds, and strong midge hatches. Key locations include the Lower Madison River, Gallatin River, and Paradise Valley Spring Creeks.

The Lower Clark Fork River is fishable, with water temperatures around 45 degrees. Nymphing and streamers are recommended. Expect cool weather and a rain-snow mix this weekend.

With ice covering Fresno and Nelson reservoirs, it's time to hit those edges—weed lines, humps and drop-offs are calling your jigs and tip-ups!

Henrys Lake anglers, let’s get you caught up on recent happenings, this year’s stocking report, and much more.
