Water flow update for the Big Horn. They just dropped the flow to 676.1 cfs. Fished ok today, things were a little off with the drop. Great Trico hatch this morning with midges mixed in attached. We’ll be on the water all weekend and will give an update asap. Keep up on Wyoming water flows:

We are a little late on passing this along, but just to clarify for all you Big Horn junkies out there, the voluntary fishing restrictions have been lifted on the Big Horn in Thermopolis! Midges are starting to hatch, so far it's been a medium gray/black/green and smaller tan/white midge, still seeing good trico hatches, some summer caddis are hanging in there, starting to see some fall caddis. The PMD's are super tiny kind of a hassle trying to imitate them. We are starting to see Mahagony Duns with a few BWO's here and there. While fish are always going to hit crawdad and streamer patterns, with the recent drop in the river we are seeing a bit less activity on that stuff. Picking up a few fish on san juans and sow bugs. So a good mix of bugs to choose from. On sunny days the fish will be deeper, if you are lucky enough to catch a cloudy day be prepared to dry fly all day long!

CODY- The Wyoming Game and Fish Department has lifted voluntary fishing closures for the Bighorn River, effective immediately. Game and Fish staff have continuously monitored stream conditions since the closures were announced in early August. Recent cooler weather has moderated water temperatures a...

Lost somewhere in cutthroat heaven...

🏔️🎣This absolute beauty slammed a streamer on one of our favorite Wyoming rivers this week. And on another the caddis hatch was remarkable on the fishing was even better.

🌡️We’ve been blessed with a nice cool down with rain and nighttime temps dropping into the upper 50’s across the state which is badly needed. Looks like a little warm up over the next couple of days, but then it gets cooler again. Hopefully the heat of the summer is behind us and our water temps will continue to drop.

Just a quick heads up that the Big Horn river is blown out. Feeder creeks from both sides are turning the river off color. It is clear until Buffalo Creek Road on one side. The other side is blown out. Once you get below Buffalo Creek Road the entire river is muddy.

With the Wyoming Game and Fish voluntary 12pm closure of the Big Horn River in Thermopolis, we are calling off trips until water temps drop to protect this great resource. Fortunately we have permits to fish the Wind & Green tailwaters and small mountain creeks like this one in our area full of willing Yellowstone trout. If you’ll be in the area and want to go fly fishing, give us a call, it’ll be an experience you’ll never forget! 1-307-864-3499

Here's an exciting article from our Wyoming Game and Fish about Helicopter stocked lakes around Dubois and Lander. As it says, it will take a few years for these fish to grow to catchable size, but these are definitely places to put on your list come 2028 and beyond! We do have permits to guide on several lakes in the Lander area, if you are interested in learning more hit us up!

🌡️ PLEASE WATCH WATER TEMPERATURES WHEN TROUT FISHING

We recently checked the water temperature coming out of the dam on the Wind River and received readings of 66°F and 67°F.

The Wind River becomes the Bighorn River at the Wedding of the Waters near Thermopolis, so these temperatures are important for anglers fishing the river downstream.

Trout are cold-water fish. As water temperatures rise, the amount of dissolved oxygen in the water decreases. This makes it much harder for a trout to recover from the stress of being hooked, fought and released.

At 66–67°F, we are already entering the caution zone. Many fisheries and conservation organizations recommend stopping catch-and-release trout fishing when water temperatures reach 68°F. Wyoming Game and Fish advises anglers not to release trout once the water reaches 70°F.

Here are a few ways we can help protect the fishery:

🎣 Fish early in the morning when the water is coolest.

🌡️ Carry a stream thermometer and check the temperature regularly.

⏱️ Use appropriate tackle and land fish as quickly as possible.

💧 Keep the fish in the water, wet your hands and avoid lengthy photographs.

🚫 When the temperature reaches 68°F, please consider giving the trout a break.

This is not about criticizing anyone for fishing. It is about educating ourselves and protecting the trout that make the Wind River and Bighorn River such special fisheries.

A trout may swim away after being released, but that does not always mean it survives. A little restraint during the hottest part of summer can help ensure that these fish are still here for all of us in the future.

Please share this information with other anglers and help us protect the resource.
