Antoine Bissieux5-Day Outlook as of 4/18/26
Today (April 18th) the flow coming out of the dam in Riverton is 171cfs and the Still river is adding an additional 256cfs making for a great medium flow of 427cfs in the TMA. Expect flows to stay consistent throughout the week.
Techniques & Tips as of 4/18/26
Nymphing is consistent catching most of the fish. Some of the best patterns to fish right now are #12-16 pheasant tails, #18-20 egg flies (for sucker spawn), and some #16-20 early black stoneflies. Small jig streamers are working well and some anglers are catching nice fish on some larger articulated flies. Look for Hendricksons hatching now in the afternoons anytime between 12pm and 5pm depending on water temps.
