Orvis Avon's Tip of the Week
Look for fish in all parts of the river this week. You will find trout in the faster water feeding on caddis pupae along with quite a few fish rising in runs and pools in the mornings and evenings primarily. Break out the dry fly rods if you haven't already and if you don't see any fish rising a dry dropper rig is an excellent choice right now with the low flows. Caddis (#14-20), Vitreus (#14), and March Browns (#10-12) are all hatching right now with mot of the activity occurring at night.

Antoine Bissieux5-Day Outlook as of 5/18/26
Today (May 18th) the flow coming out of the dam in Riverton is 132cfs and the Still river is adding an additional 74cfs making for a medium-low flow of 206cfs in the TMA. Expect flows to stay consistent throughout the week with minimal rain in the forecast.
Techniques & Tips as of 5/18/26
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.
