Henry’s Fork

Henry’s Fork 8-31-13

Most reliable part of the river for fishing is the Warm River to Ashton stretch. During daytime hopper and chernobyl patterns trailed by a bead head nymph or rubberlegs trailed by a bead head nymph pattern bring action.  Big browns are reacting to streamers early and late in the day. Evening and morning streamer fishing will become more effective as we move through autumn months.

It’s the time of year when trout  move into the river above Island Park Reservoir. Reasons include the less hospitable conditions in the drawned-down reservoir, kokanee beginning to migrate, and a remnant spawning run. For now try the river below Coffee Pot Rapids. Streamers and wooly bugger types work for wets while hopper, traditional attractor, and caddis patterns work well for dries.  Consider soon trying the river just below the Big Springs-Henry’s Lake outlet confluence with streamers and terrestrial patterns.  But do so late or early in the day to avoid the boaters.  As we move into autumn, this part of the river will host some very large rainbows.

Likely the most reliable location for action on the river these days is the Warm River to Ashton stretch.  Hoppers with a small bead head nymph dropper produce during daytime.  So does a two nymph rig of rubber legs trailed by your favorite bead head nymph (size 12-16). Try streamers in the evening to interest those big browns.  Caddis  life cycle patterns will interest the smaller fish.  Until we cool off forget the river below Ashton Dam where water is warm enough for swimming.  On the upper river consider walking downstream from Riverside Campground to present hopper and caddis life cycle patterns during the evening. Concentrate your fishing efforts early to mid mornings on the Harriman State Park stretch were spinners will be interesting trout.

Morning spinner falls offer the best fishing on the Harriman-Last Chance reach of the river. After that switch to terrestrial patterns and hope for a cumulus cloud build up that means increased relative humidity. This action could result in enough speckled duns to interest trout. Towards evening look for some caddis activity. But when the sun goes behind the hills to the west, put on that hair mouse pattern, and place it near an undercut.  You may get nothing, but if a trout responds it is certain to be very large—maybe the trout of the year for you!

Even though the flows are slightly higher than normal, the lower river is already in the summer doldrums because of the early warm weather.  In the Last Chance-Harriman part of the upper river, all the drake hatches are over and some PMDs remain, but fishing has slowed because of warm weather and recently increased flows out of Island Park dam.  When speckled duns and hoppers become important look for fishing to pick up big time. “Fish early, fish late” applies until then.  Same applies to the lower river, and don’t overlook trying your favorite streamer during sunset to twilight or around sunrise.

Folks at Henry’s Fork Anglers (HFA) tell us that brown drakes are well past their peak, but flavs are coming on through the Harriman State Park reach of the Henry’s Fork. It’s mostly a PM event.  So pay HFA a visit for the best current information, and also visit a Last Chance eatery for that hearty lunch to fuel up to meet those big afternoon rainbows taking flavs!


Henry’s Fork 7-2-13

Green and gray drakes are winding down now on the upper river, but flavs and brown drakes are coming on. PMDs remain a major attraction for feeding trout here.  Best time for flavs on the upper river is afternoon. For brown drakes best time is evening, and the lower end of the Harriman State Park reach offers the best numbers of these drakes.  You will have plenty of company during these destination events, but the beauty of the area and the size of the fish makes a visit worthwhile.


Henry’s Fork 6-29-13

On the upper river flavs have begun showing, but green drakes and PMDs are still bringing much action in the Harriman-Last Chance area.  It appears that these mayflies are hatching in numbers as good as any in recent years, and fishing is great because of it.  So get up there, and enjoy!  Here’s a thought: be sure to have a few of your favorite dry golden stone patterns in that fly box. Those older fish know what they are, and will take them. You may get fewer fish than those folks presenting mayfly life cycle patterns, but the fish responding to that golden stone pattern will average bigger sizes.  On the lower river gray drakes and PMDs remain numerous and provide good fishing, but look for water to begin warming because of our hot weather.


Henry’s Fork 6-24-13

Fishing on the Henry’s Fork is very good right now. There are a bunch of bugs hatching and the fish are looking up.  The entire river is fishing well, but we have heard very good things on the river below Ashton and up in the Ranch/Woodroad #16 area.  Everything from Green Drakes, Yellow Sallies, Flavs, Caddis, and PMD’s are coming off. Fish were really keying on the drakes last week so make sure you have plenty of drake patterns on you. Nymphing with a rubberleg/attractor dropper set up and Streamer fishing have been very good too…  Get out there while its hot!

Now is a good time to go back to the Cardiac Canyon reach with dry golden and giant stonefly patterns. The giants and golden hatches went through big time a few weeks ago, and fish have had a chance to digest those eaten.  Fish remain conditioned to look for these, so a good strategy for such as Hatchery Ford, around the Mesa Falls area, and Bear Gulch is to present them.  You may not get into quite as many fish as during the peak of these hatches, but you will surely have good results.  Cardiac Canyon keeps you away from crowds on the Harriman-Last Chance reach above looking for responses to green drakes, caddisflies, and PMDs and from the crowds on the river below responding to the gray drake hatch.  Speaking of green drakes, they’re ramping down on the lower river and yet to make  a major appearance in the Last Chance-Harriman part of the river.
