Henry’s Fork

Henry’s Fork 4-29-14

Now is a good time to visit the lower Henry’s Fork. Flows are slightly less than normal, and look for water temps climb to the mid 40s in deg. F by late afternoon.  A good caddis emergence is ongoing and peaking in the afternoon. BWOs are also emerging during the PM hours, especially if weather returns to what it was last weekend. Then there are the ever present midges. March browns should become significant any day.  Don’t put away those streamer patterns just yet; save them for evening presentations.


Henry’s Fork 3-20-14

The Henry’s Fork is fishing really well right now. Streamers are the ticket in evenings, early mornings, and under low light conditions . BWOs are beginning to show up in good numbers, and midges seem to be emerging always. Try your favorite rubberleg pattern presented close to the bottom and under an indicator


Henry’s Fork 3/4/14

Snow and ice are beginning to leave the lower river making access easier.  Water temperatures still hover just below forty degrees F., so midges continue to provide top water activity.  Emerger patterns presented in the surface film or just below are best bet for action.  No word on good BWO emergences yet because warmer water is needed.  Streamers are a great way to encounter larger rainbows and browns, especially below Chester Dam.   Concentrate efforts on deeper water and around overhead cover out of direct sunlight. Low light conditions will always be best time for streamer fishing. Above the Chester back waters to the Vernon Bridge (river is closed to fishing until general season opening from there up to Ashton Dam) add big stonefly nymph patterns as being effective for larger trout.  Come to the shop and talk to us about specific locations


Henry’s Fork 11-5-13

Top water action (BWOs and midges) has slowed a bit on the lower river. When skies cloud up, the best way for action is to present streamers.  Early and late in the day will be the best times to give them a try cloudy skies or not.  Flows throughout the lower river are somewhat lower than normal, so there are plenty of good locations for wading.  Some of the best streamer fishing on the upper river can be enjoyed in Box Canyon where flow out of Island Park Dam is just under 100 cfs. Thankfully Buffalo River adds another 200 cfs.  If you enjoy presenting streamer patterns other great locations are “The Tubs” area above Macks Inn and below Coffee Pot Rapids. It is getting close to winter in Island Park, so dress accordingly!


Henry’s Fork 10-26-13

Nearly everything we offered in the latest South Fork fishing report applies to fishing the lower Henry’s Fork.  Water is low and walk-in wade locations are abundant from just upstream of the Wendell bridge to below St. Anthony.  Brown trout are migrating throughout with BWOs and midges emerging, but all these are best during overcast days.  The river in Island Park and below Island Park Dam is also low with only 19 cfs coming out of the dam. This makes inflow from Buffalo River very important.  Nevertheless the river at Last Chance and into Harriman State Park is choked with weeds, but BWOs are active with some fish working.


Henry’s Fork 10-18-13

The Henry’s Fork is fishing really good right now. The entire lower river below Ashton has been producing well with nymph rigs, streamers, and BWO’s on overcast days. Nymph wise throw a rubberlegs and smaller bead-head dropper. It is getting to be the time of year when egg patterns work very well too. Streamer fishing has been great and the pattern doesn’t seem to matter too much, but flies like the sculpzilla and Kelly Galloups Peanut Envy have worked particularly well. For those wanting to float, stretches like Ora to Vernon or Ora to Chester have been popular, but wade fishing has been just as productive. The weather for the weekend looks great, so get out there and enjoy some of the best fishing of the year!


Henry’s Fork 10-12-13

Flow out of Island Park Dam is reduced to 84 cfs. This is very tough on boating but great for walk-in wade fishing.  Small bead head nymphs are a best bet, but do not overlook streamers during low light conditions. Elsewhere on the river cool cloudy weather will bring out BWOs big time and resulting interest from trout, but hinder mahogany duns.


Henry’s Fork 10-8-13

The lower river is fishing very well with BWO and mahogany dun hatches providing good top water fishing with emerger, dun, and spinner patterns.   Don’t overlook the numerous midges on the water.  Look for some very good fishing action coming up as we expect some stormy weather from now to the rest of the week.  Under low light conditions streamers will be effective earl and late in the day.


Henry’s Fork 9-28-13

Best news here is that the recent cool, wet weather has brought the lower river back to life. Mahogany duns, BWOs, and midges are making for great dry fly fishing.  Early and late in the day streamers are attracting large trout around overhead cover.  On the upper river flow out of Island Park Dam is around 300 cfs as water storage kicks in.  Try two-nymph rigs during daytime. When clouds prevail try high-sticking big stonefly nymphs.  Switch to streamers as daylight fades.


Henry’s Fork 9-17-13

This is the best time of year to fish the river above Island Park Reservoir.  Large rainbows are moving out of the reservoir, some to follow kokanee, others to escape the warming water, and others to begin a spawning run.  With flows out of Henry’s Lake dropping, trout in the Outlet reach move downstream to the river for better habitat.  Thus the river from the reservoir upstream to the Big Springs closure has an added compliment of large trout.   Although this part of the river does not have the great and varied aquatic insect population of the river below Island Park Reservoir, it has caddisflies and midges in abundance and the banks host plenty of terrestrial insects. From the Coffeepot area downstream to the reservoir stoneflies are important.  But is worth remembering that the fish that have moved in originated in either Henry’s Lake or Island Park Reservoir. Thus some of the favored flies on these still waters can be effective, especially streamers and wooly bugger types.  So consider this part of the river to be a destination this time of year. You will have a great chance for encountering some large rainbows and cutthroat
