Orvis Avon's Tip of the Week
Runoff season is here and there is still plenty of snowmelt in the woods that will contribute to these early season higher flows. Be careful wading the river in these high cold water conditions. Nymphing slower current seams and staying close to the river banks are the best way to find fish right now in these high conditions. Cycle through different flies if you aren't catching fish and be patient, all it takes is a slight bump in water temp to get the fish feeding. Trout are still in early season mode which means most are holding in slower moving runs. You may find some fish sliding into faster water to fed when temps are at their highest but it will be a few weeks before we see trout consistently in the riffles.

Antoine Bissieux5-Day Outlook as of 3/13/26
Today (March 13th) the flow coming out of the dam in Riverton is 157cfs and the Still river is adding an additional 860cfs making for a very high flow of 1017cfs in the TMA. Expect flows to stay high throughout the week and water temps to only slightly increase.
Techniques & Tips as of 3/13/26
Nymphing is consistent with small flies catching most of the fish. Some of the best patterns to fish right now are #18-22 midges, #18-20 egg flies, #16-20 early black stoneflies, and #16-20 pheasant tails. Small jig streamers are working well at times and some anglers are still catching nice fish on some larger articulated flies fished with a slightly slower retrieve. The dry fly fishing can be okay depending on the day, winter caddis will still hatch most mornings in even the nastiest weather for the dry fly purists. Midges will hatch many afternoons as well which can bring some nice trout to the surface along with early black/brown stoneflies that have recently started to hatch in pretty good numbers.
