Orvis Avon's Tip of the Week
Before you step foot in the river take a water temp! Flows are low and even though the water coming out of the dam is cold, it is heating up very quickly downriver. Look for water temps below 68 degrees and ideally temps below 66, the colder the better for catch and release! The evening dry fly action has been pretty good up river. Small sulphurs and Attenuate are still hatching in the upper TMA and throughout Riverton. Isonychia are still hatching consistently throughout the river in the fast water.

Antoine Bissieux5-Day Outlook as of 7/13/26
Today (July 13th) the flow coming out of the dam in Riverton is low at 134cfs and the Still river is adding an additional 21cfs making for a low flow of 155cfs in the TMA. Expect flows to stay consistent throughout the week with little rain in the forecast.
Techniques & Tips as of 7/13/26
Dries, nymphs, and streamers will all catch fish right now. The dry fly fishing in particular has been excellent some days with lots of fish rising in the evenings. Nymphing is good regardless of the time of day and there are plenty of ways to do it. Tightline nymphing is great but the dry-dropper fishing is excellent right now and you can still definitely run an indicator rig with plenty of success. With the flows being low and clear it's not a bad idea to downsize tippets to 6x for nymphs/dries unless you're throwing a larger fly like a March brown. If you are fishing streamers and want to throw some larger articulated patterns your best bet is after a strong rain which we will hopefully receive soon that will bump the flows up. Some of our smaller-medium sized patterns are working very well that we have in stock in the store tied locally by Rich Strolis.
