Bighorn River Spring Bite: Sowbugs, Streamers, and 70 MPH Winds

Howdy, folks, this is Artificial Lure, your go-to gal for all things fishin' down here in Big Horn country, Montana. It's Friday mornin', March 13th, 2026, and we're lookin' at a prime day to wet a line on the Bighorn River near St. Xavier and Fort Smith. Weather's a tad warmer than up in Bozeman—think upper 30s to low 40s—but brace for those gusty winds howlin' up to 70 mph in spots, per Montana Outdoor reports. Sunrise hit around 7:15 AM, sunset 'bout 7 PM, givin' us a solid 12 hours of daylight to chase bites. No tides here in our river stretch, but stable tailwater flows from Yellowtail Dam keep things clear and fishable. Trout are feedin' steady despite the breeze—rainbows and browns hammerin' sowbugs and scuds all week, with sowbugs dominatin' into spring. Folks been pullin' limits: 15-20 inchers common, some pigs to 24 inches on streamers. Nymph rigs are killin' it—a sowbug or scud trailed by an Olive Micro Mayfly, Pearl/Olive Jiggy Perdigon, or Pheasant Tail. Streamers? Surprisingly hot: Sparkle Minnows, Skiddish Smolts, Wooly Buggers, and Thin Mints for the big boys. If you're bait fishin', tip jigs with worms or maggots in deeper slots. Hot spots today: The 13-mile stretch below Yellowtail Dam—focus on deep seams and tailouts near Fort Smith for nymphs. Down by St. Xavier, hit protected bends outta the wind for streamers. Wade careful, add weight to fight the gusts, and fish slow—trout are active but picky in this cold tailwater. Tight lines, y'all—get after 'em! Thanks for tunin' in, and don't forget to subscribe.
