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. 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 7/21/25
As of today (7/21) the flow coming out of the Goodwin Dam in Riverton is 249cfs and the Still River is contributing an additional 55cfs making for a medium flow of 304cfs in the TMA. Look for flows to stay consistent goes on. Attenuate, Isos, Caddis, and BWOs are the main bugs that are hatching right now with Sulfurs taking a backseat other than in Riverton where there are still a few hatching. Some of the best hatch activity has been the last 45 minutes before dark so be patient and wait for the bugs if you can!
Techniques & Tips as of 7/21/25
If you can get out in either early-mid mornings or evenings you will likely see trout rising to a variety of bugs. 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 caddis, sulfurs, and olives in the flat water.
