Big Horns Trout Challenge: Nymphing for Trophy Rainbows and Browns on Montana's Premier Tailwater

As of November 28, 2024, the Big Horn River in Montana is offering some challenging yet rewarding fishing conditions. Here’s what you need to know for a successful day on the water. ### Weather and Water Conditions The weather is expected to be partly cloudy with daytime temperatures in the mid-50s to low 60s, making it comfortable for fishing. Nighttime temperatures are cooler, causing aquatic grass to break off and affect some of the runs. The river is flowing at about 2,200 cubic feet per second, and the water temperature is around 50 degrees. ### Sunrise and Sunset Sunrise is at approximately 7:15 AM, and sunset is around 4:30 PM, giving you a good window to catch both the morning and afternoon bites. ### Fish Activity Fish activity is primarily subsurface, with trout actively feeding on nymphs in the deeper runs and holes. Nymph fishing has been the most effective method, with San Juan Worms, scuds, sowbugs, and Perdigons being top producers. There are also some Pale Olive Baetis and midges hatching, but surface action is spotty. ### Types and Amounts of Fish The Big Horn River is renowned for its healthy population of rainbow and brown trout. While the fishing has been a bit hit and miss due to the breaking off of aquatic grass, you can still catch some big fish, particularly on streamers. ### Best Lures and Bait For nymphs, use #14, #16 Orange Scud, #14, #16 Tailwater Sowbug, #16 Carpet Bug Sowbug, and #10 Squirmy Worm (blood red or burgundy). San Juan Worms are also highly effective. For streamers, try #6 Thin Mint Wooley Bugger, #4 Articulated Goldy, or #4 Rusty Trombone. ### Hot Spots Focus on the deeper runs and holes where the water is cleaner and less affected by the floating aquatic grass. The upper sections of the river, particularly below the Afterbay, tend to have clearer water and better fishing conditions. Also, look for areas with less grass break-off, as these will increase your chances of catching fish. Overall, the Big Horn River is still a great place to fish, even with the current challenges. Be patient, keep your bugs clean, and you'll have a good chance of landing some trophy trout. This content was created in partnership and with the help of Artificial Intelligence AI.
