Big Horn River Fishing Report

The Big Horn River in Thermopolis, Wyoming is the lesser known sister of the Big Horn in Fort Smith, Montana. An intimate tailwater which meanders through the farm fields and ranches of the Big Horn Basin, the river hosts Browns, Rainbows and Cutthroat trout. These fish grow large and fight hard, making for fun and challenging fly fishing. The Big Horn can be an excellent dry fly fishery - if conditions are favorable, trout will readily eat mayflies, cicadas, grasshoppers, crickets, ants and stoneflies during sometimes prolific hatches. Of course what happens on the surface is only part of the story. Trout fodder is abundant in the Big Horn, and often the best way to find fish is to go subsurface. The river fishes well in all seasons, and as we live right here in Thermopolis, we offer guided trips year round. A guided float trip is the best way to get the most out of this section of the Big Horn - due to water laws and private ownership, much of the river is not open to anchoring and wading. That being said, there are some spots where you could get out of the boat and wade fish if this is of interest to you. We invite you to come experience some of the best fishing Wyoming has to offer with one of the fishiest husband & wife teams in the West.

Fished with Larry and Ray today, just a half day, which is perfect for the amount of fishable water right now. Buffalo Creek is on round 2 of dumping in red mud. It had cleared pretty ... moregood after last week's rains but I guess we got quite a bit of snow up in the Bridgers and with the warm weather the last few days it's got the creek flowing good. River is MUDDY after the red cliffs. But with all that said we had a pretty good day. Hooked about 30 of these.

Lots of break offs today. Fat feisty rainbows on 5x. Baetis nymphs were our best bugs. Saw a few guys out there today throwing streamers only saw one boat get one. Other boats said no good. But it is a good option in the dirty water. Hoping the river clears by the weekend but we are forecast to get a little more rain. So we'll see. River is at 990cfs. And we have a few trips going out next week but still plenty of days available if you're interested. Also the dry fly fishing is still pretty good, at least it was on Tuesday when I went out with Adam. Besides the bwo's we are seeing quite a few caddis and a lot of fish are taking notice and even moving out of their feeding rhythm to eat them. And a minor psa, please respect the property owners' rights... it is private property from the first highway bridge below wedding all the way past buffalo creek and the red cliffs. We don't need this place turning into the reef. Have fun out there!
