Fall on the Bighorn

Fishing Report 9/26/17

Flows: 4250 CFS

Water Temp: 64

Fall is officially here to stay on the Bighorn. With outside temps dropping and river flows increasing, fishing on the ‘Horn has been great. Tricos are still here, though are hatching a bit later in the day as the temperatures are dropping. Psuedos, Blue Wing Olives, Midges, and Black Caddis continue to be the evening options for dry fly fishermen.

Nymphing has been consistent as of late. Mayfly patterns, sowbugs, midges and worms are getting the job done. Running a 7 foot leader with a 3/0 split shot is necessary to get the bugs down. Shorten your set up to 4-5 feet when wading the shallow, clean gravel runs.

Streamer fishing is coming into shape for the fall. The bite has been consistent as the air temps cool down. Running a size 4-6 white or olive pattern up front and trailing it with a small bugger or leech pattern has been lights out. Again, key in on the skinny water with clean gravel.

Yes, river flows have gone up, but don’t let it scare you away from the Bighorn. With an increase in our flows it is both dropping our water temps as well as blowing out the aquatic grass. The river is still very wader-friendly at these flows, and the fish are still willing to play.
