Fall Fishing on the Bighorn River: Nymphs, Streamers, and Rising Trout

As of November 1st, the Bighorn River in Montana is offering some challenging yet rewarding fishing conditions. The water temperature is around 57 degrees, and the river is flowing at about 2,250 cubic feet per second. The weather forecast for the week is looking pleasant, with temperatures in the 80s, although the cooler nighttime temps are causing aquatic grass to break off, which can affect some of the runs. Look for the clean lanes to increase your chances of catching fish. Fish activity has been fair, with nymph fishing being the most consistent method. San Juan Worms have been the primary producers, but you can also catch fish on scuds, sowbugs, and Perdigons. There are some Pale Olive Baetis and tricos around, but surface action is spotty. Streamer fishing has been mediocre, but using patterns like Jig Thin Mints, Pete’s Buggers, and Rusty Trombones can still yield results. Yesterday, anglers caught a mix of wild rainbow and brown trout. The upper three miles of the river have some grass growth, but below that, the river remains clean and is fishing very well. You might see some rising fish, particularly in the top 13 miles, where they are eating midges, midge clusters, and a few Blue Winged Olives. For the best results, use nymphs such as the #10 Squirmy Worm, #14 and #16 Orange Scud, and #16 Tailwater Sowbug. Dry flies like the #22 CDC Baetis and #22 Trico Spinner can also be effective, although the dry fly bite is winding down. Hot spots include the area around the Bighorn Access site, where the trout population is highest, and the stretch below the Yellowtail Dam, which offers wide open country and a diverse range of fishing opportunities. Floating the river can help you cover more water and increase your chances of finding active fish. Sunrise today is at around 7:30 AM, and sunset will be at about 5:00 PM, giving you a good window to get out on the water and enjoy the fall fishing on the Bighorn River.
