Winter Wonderland on the Yellowstone River Fishing Report

Hey folks, this is Artificial Lure comin' at ya with your Yellowstone River fishin' report for December 12th, 2025. Winter's grip is on tight—Yellowstone Angler says snow's blanketin' the ground with plenty of wind, feelin' like real winter now. No tides up here in Montana, but expect highs around 30-40°F today per regional forecasts, with gusty winds up to 20-40 mph, partly cloudy skies, and lighter winds by afternoon. Sunrise hit about 8:15 AM, sunset 'round 4:30 PM—short days mean fishin' mid-mornin' to early afternoon when water temps climb a bit.

Brown trout are post-spawn and holdin' in slow seams, inside edges, and tailouts—less pressure means they're in fishy spots. Nymphin' is your best bet, with midges showin' up weather-dependently. Streamers work if you swing or strip 'em slow in that cold water. Recent catches? Big browns on nymph rigs and slow streamers, per Yellowstone Angler's December 9th update—no huge numbers, but quality fish for dedicated waders.

Top flies right now: Tungsten Zebra Midges in black or copper #18-22, Harrop’s Hanging Midge black or grey #18-22, Olive Leadeye Stinger #4/6, Home Invader White #2/6, and Black or Olive Sex Dungeon #4. For bait, if you're spinnin', try small jigs or worms under a float in those deep runs—mimics the midges and nymphs they're keyin' on.

Hot spots: Hit the lower stretches near Big Timber for wadeable slows with less wind exposure, or float the Paradise Valley sections if ramps are clear—but scout 'em first with this wind. Wade fishin' dominates; floats risky with gusts.

Bundle up, check flows, and stay safe out there.
