Fishing reports focusing on the Henrys Fork in the Ashton/St. Anthony area.
The water temp is like 70 degrees now and the fish are down deep so the only thing working now is throwing streamers on the banks and nymphing most of the time use a rubber legs stonefly and drop of some sort of a beaded nymph like a prince in about a size 12 or 14 that should work well.
It seems the really hot fishing below the Ashton dam is off a week or two. I fished using a caddis and had a couple fish strike and landed a small brown, but my hope was getting into consistent rising, which was not happening. Looking forward to the big mayfly hatches that usually start up in mid June. Even if the fishing is slow there is nothing better than being on the river. Good luck!
The salmon flies are just finishing up in the box so use a salmon fly as an indicator and drop off either a stonefly nymph or a small copper john or other small bead head.
This section is fishing good people are getting nice fish on this section use a golden stone with a copper john dropper or some other small bead head. If the weather is cloudy try streamers on the bank.
This section is fishing pretty well Early morning use streamers on the banks and nymphs like a salmon fly or golden stone nymph and drop off a copper john or a pheasent tail or prince nymph
There are still reports of a lot of big bugs on the Warm River to Ashton section of the Fork, but the fishing has slowed to a stand still. The fish must be stuffed to the gills. The hatch is moving up river making the slide below Lower Mesa to Warm River a good bet. Hatchery Ford and higher would be good spots to hit to take advantage of one of the most exciting hatches of the year.
Just caught word that the Salmon Fly's are indeed hatching on the Fork. Vernon to Chester and Warm River to Ashton are on fire. Go get ya some!
The Henrys Lake outlet fished very well recently. We caught several fish - mostly small, but a couple of nice 15" + fish all on a black and red Chernobyl Ant with a prince dropper.
The word on the street is fishing is better in the high elevations with the relentless heat baking the waters in the valley, so Island Park is the place to be. Also heard the South Fork was fishing better than it has in years, but that flows were up due to the need for water downstream.
The caddis are thick on Warm River to Ashton. Big fish start feasting as soon as the sun stops beating on the water. Find a shady edge of river and toss that infamous caddis. Fish after fish over 18 inches was the rule of the night. With the heat getting up there in the day, the best time to fish is after 6 PM or before noon.
