Flows have gotten pretty large on the Henry’s Fork. The lower river starting from Warm River confluence is pretty dirty and muddy. The river at St. Anthony is at Flood Stage. Water from the Box Canyon down to the Warm River is in pretty good condition. Fish nymphs under an indicator. Stonefly nymphs and caddis pupa are working well. There should be some dry fly caddis buzzing around but no report of fish actively feeding on the surface.
With the Holiday weekend coming up there will be a lot of people who migrate to The Box Canyon mostly cause its the only game in town. Just remember to be courteous and use some common sense.
