Orvis Avon's Tip of the Week
Before you step foot in the river be sure to take a water temp. If you get a reading above 68 degrees you should either move upriver to find colder water or stop fishing all together. The mortality rate is very high if trout are caught and released in warm water temps so be mindful of where you are fishing. Nymphing early mornings is a great way to catch fish before most of the other anglers get out on the water. Tricos have been hatching consistently throughout the river and the spinner falls have been bringing some nice trout up to the surface. Look for Trico spinners to fall when air temps reach about 68 degrees on mornings/evenings with minimal wind. The terrestrial fishing has also been productive mid-day when not much else is going on. When fishing with ants/terrestrials target shady banks mid-day and you will likely get some fish to rise to the larger bugs.

Antoine Bissieux5-Day Outlook as of 8/10/25
As of today (8/2) the flow coming out of the Goodwin Dam in Riverton is 243cfs and the Still River is contributing an additional 19cfs making for a nicemedium flow of 262cfs in the TMA. Look for flows to stay consistent as the week goes on. Tricia, Isos, Cahills, Caddis, and BWOs are the main bugs that are hatching right now Some of the best hatch activity has been early morning and the last 45 minutes before dark so be patient and wait for the bugs if you can!
Techniques & Tips as of 8/10/25
Trout are receiving an education from quite a few anglers on the river so now is the time to dial in your presentation. Longer leaders around 12' are an excellent choice for fishing dries and 6x is a good choice for presenting smaller flies like Tricos and olives in the flat water. Dry dropper rigs are another excellent choice when fish aren't actively rising.
