The section from Warm River to Ashton has been fishing quite well lately. Anglers have been catching lots of trout using standard nymphing rigs consisting of a large rubber leg nymph dropped with a small bead head. Fish this set up through long tailouts and along the banks if you are fishing from a boat. Another combination is the dry dropper with also has been working well. Be sure you allow plenty of room between the dry and the dropper to get you nymph down as far as you can handle. The section from the dam to St. Anthony's is hot. Huge trout are being caught on stoneflies with a rubber leg dropper. This section needs to be fished slow and smart. Around every bend you can expect to see something different. Have a spare rod set up with weighted stoneflies and be ready to drift that rig right along the bank.

From the Warm River to the Hwy Bridge and the section from Ora Bridge to Vernon Bridge the river is around 1070 csf. Bring plenty of BWO's and Midges in various sizes along with their emergers because that's what up on the Henry's Fork today. Of course nymphing is always effective on these two stretches so be ready for that too. This is probably one river that is in the best shape for fly fishing during this early Spring run off.
March 25, 2011
Below Ora Bridge, below the dam the fishing has been spotty but if you time it for the warmest part of the day you may have a great day fishing this particular section of the Henry's Fork. Start out using a double nymph rig of bead heads and keep your eyes open for feeding trout on baetis and midges. The same can be said for the section from Vernon Bridge down to St. Anthony.
August 26, 2010
The section of water between Warm River and Ashton Bridge is your best bet on the Lower Fork. Dog days of summer have also arrived on lower river with nymphing and late evening caddis your best shot.
June 20, 2010
In the day's to come you should keep your eyes open for Flav'v, Green Drakes, PMD's and evening Caddis. The hatches on the section from Ashton dam down to Chester Diversion can be awesome. Don't Fish this section without these may flies in your box along with a good selection of emmergers to go along with them. Right now the Aston stretch is best fished midday with big nymphs dropped with a bead head nymph with enough weight to slow your drift down. Warm River to Ashton Res. has been fishing good using the above nymph rig. You might see some March Browns and PMD's on this upper strectch but for the most part it's been best fished nymphing.

The Warm River to Ashton section of the Lower Henry's Fork is a hit and miss situation right now. Some anglers are doing rather well while others you talk to are not. This is primarily a nymphing section and you should be prepared to do just that. Baetis, March Browns and Some PMD's in the afternoon and you should see some Golden Stones and Caddis in the later afternoon to evening. You should have two rods hooked up; one for nymphing and one for dry fly. If you are up that way it would do you right to float this section. It's a eight mile section that can be floated in a few hours in higher water. The Ashton to Chester Dam section is where I would concentrate on. Good nyphing with big bugs like Woolly Buggers and Stone Fly nymphs dropped with your favorite bead head nymph with drag up some really large brown trout! Look for the same bugs that are on the Warm river to Ashton section.

If you live in the general area or don't mind the drive the lower Henry's Fork from Warm River to St. Anthony's may be worth your effort. Most of the river bank is snow free and anglers are catching a fair amount of trout and white fish. Concentrate on working the riffles and deep quick runs with nymphs and streamers and stay away from nymphing the flats. Watch for rising fish who may be working BWO or midges.
March 22 ,2010
Midge fishing and nymphing for trout from Vernon Bridge all the way to St. Anthony is what the Henry's is offering any angler willing to travel the Fork. Persistent anglers are catching some pretty good rainbow and brown trout on good days. The weather is warming and the roads will start to be clear of snow but the overall picture is still winter fishing. Look for BWO's to start the season off in the next couple of weeks and by April hope for some caddis action.
March 1, 2010
With much of the upper sections still closed the Lower Henry's Fork from St. Anthony's up stream to Vernon Bridge can offer some pretty good fishing depending on the weather the day you are there. Midge fishing the sections just below the tailouts can bring home some nice trout. Of course white fish can take up the slack if your not seeing any rising trout. The best thing to do is be casual and visit as may access points as possible until you can find a pod or two of rising trout.
October 27, 2009
From the Warm river confluence to St Anthony's the Beatis Mayfly has dominated. You must have two rods ready on for casting small BWO's and emergers and the other for casting large nasty streamers for pre spawn Brown trout. This is arguably the best time of year to be on the Lower Henry's Fork for the top water action can be incredible. Be sure to have a good selection of Baetis patterns in small sizes from dries and emergers to cripples and nymphs. You won't be disappointed.
October 7, 2009
Finally! with the colder weather the Baetis action has been unstoppable. Size 18 and 20 BWO's with an Baetis emerger will get you into the trout. The early evening or late afternoon is when the action really takes off. During the day nymph the likely looking holding areas and don't forget you'll still see hoppers and other terrestrials out and about.
September 23, 2009
Stimulator's, Annihilator's, Hopper's, Chernobyl's and Madam X's with bead head droppers are what's being used in the Henry's from Warm river to St. Anthony. This section is also a good nymphing section and yous should have your nymphing rod at hand. The evenings are still showing a decent Caddis hatch and you might start seeing some BWO's also.
September 15, 2009
The section from Warm River to Ashton is starting to get better. The water temps are starting to go down and the PMD action is still going strong. From Aston to Chester the river is near 1600 cfs and the Baetis action is just beginning. Work the river with n;ymphs and streamers during the day and look for a good Baetis hatch starting around 3:00 and last until dark.
September 4, 2009
From the Warm river confluence to St. Anthony the Henry's Fork lower section is in summer time mode. Early morning and early evening seems to be the best time to fish. During the hot day use Hopper's and other terrestrials along the banks and work your nymphs through deep pools and tail outs.
August 24, 2009
The sections from the Warm River to Ashton and Ashton to Chester remain the same. Nymphing and Hoppers are what anglers are using to catch their Trout on these sections. Look for and evening hatch of Caddis and some Baetis around Vernon Bridge.
August 17, 2009
Warm River to Aston the rivers running around 1300 cft and fishing has been somewhere between good and slow. Most fish are being caught using an attractor fly such as a stimulator or annihilator with a bead head dropper. This stretch of water is known for it's nymphing so be ready to work the deep holes and long runs with your nymph rig.
August 5, 2009
The Warm River to Ashton section of the Henry's Fork is probably the best section to fish on the Henry's at this time. This section is known to be good nymphing water and this hold true for the time being. Use you tradition nymph rigs but be sure to use enough lead to keep your nymphs moving along the bottom. Watch for PMD's and the Trout lining up to take them. On a spare rod have a Parachute PMD with a PMD Emerger as a dropper. Concentrate on pocket water, drops and tail outs. Don't spend time working the flats, use your time on the better producing water.
July 22, 2009
The water level below Ashton Reservoir has dropped significantly enough to warm up the river during these hot days to a point where you might try another section or river. Your best bet here is to fish nymphs in likely holding areas and deeper water. Hoppers are always a good fly to go to with a bead head dropper. When evening comes around and it's a little cooler wait for the caddis to hatch and use a good emerger imitation for good results.
June 25' 2009
This section of the Henry's Fork is exceptional right now for drift boat or raft fishing. Look for PMD's from mid morning on through the afternoon. Also Green Dakes have be seen as well as Flav's. If you plan on fishing this section of the Henry's be sure to have your nymph rod with you. Use a weighted Stonefly nymph with a bead head dropper or a large streamer fished deep among the rocks.
June 16, 2009
The section from Ora Bridge to Vernon Bridge is the place to be in Idaho at least. Large Browns are being caught on Salmon flies. Most guys are using a large bug as a dropper but the action I've seen lately has been on dries by Ora Bridge. Down at Vernon it's a little easier to wade the you might find some PMD's and some Caddis action. If you have a boat make the two and a half mile float last five hours. Anchor the boat a lot and work the rock lines with weighted nymphs after working the big Salmon fly.

June 12, 2011
The Box Canyon section is flowing at around 1400 cfs and is quite boatable and fishable using standard nymph rigs and streamers. The Ranch section is closed but will open on June 15th.
March 25, 2011
Closed until opening day
August 26, 2010
Dog days of summer have hit the Fork. On the upper section the Box Canyon area is fishing pretty well,the water flows at or near 900 cfs. Probably you best chance of a good days fishing will be on this section. The Ranch section has been fishing very slow. The best way to fish this section is to just enjoy the walk and the beauty of the area and hunt for active fish. Once you find them then the work begins. You may see some flying ants or some Caddis coming off in the evening. It's best to check in with one of the fly shops because the conditions change daily.
June 20, 2010
Box Canyon is setting the world on fire with many 18 to20 inch rainbows being caught on a regular basis. Use the standard nymph rig with a large rubber leg nymph (weighted if possible) dropped with a size 114 or 16 bead head nymph. The water level is only at 1200 cfs right now so the floating of the river should be slow enough for you to get to the most productive parts and really make a day of it. The Ranch just opened up on June 15th with mixed reviews. PMD's, Caddis, March Browns and Baetis are on the Menu for feeding trout. Look for fish that are feeding and present you flies with the best presentation as possible with no drag and you should do OK. Don't waste your time fishing blind, only fish to working fish on the surface.
June 1, 2010
The Harriman Ranch section is closed until June 15th. However the Box Canyon section from the dam to the ranch is open and some very large trout have been taken this opening day. The is your classical nymphing water and should be fished with a large nymph, small nymph tandem. Some anglers are using large foam flies with a couple of nymphs dropped below with some success.
Closed until Memorial Day weekend
October 27, 2009
The Box Canyon section is still fishing fairly well using nymphs and streamers. You are going to see some nice Baetis action here this time of year and should have you nymph rod ready for pre spawn and spawning brown trout. Work the pockets and seams of tailouts with a Parachute BWO and a bead head baetis or bead head Pheasant Tail before going to your nymph rod. The Ranch is still having blanket hatches of Baetis in the late afternoon so be ready with a good selection on Baetis patterns for sight casting to feeding trout. This can be some of the best sight fishing of the year so if you are planning a trip that way definitely fish the Ranch section of the Henry's Fork.
October 7, 2009
The Box Canyon is now at 325 cfs and the fishing has been pretty good using traditional tandem bead head nymphs to bring in the trout. A lot of anglers wait until this time of year to fish the Box because of the easy wading allows easier access to holding areas that you just can't get to any other time of year. The Ranch Sections has finally turned on to some of the best fishing all year. Blanket Baitis hatches up and down the Ranch has brought to fish up for easy meals. Be sure to bring quite a variety of BWO imitations including various emerger and cripple imitations. These fish can be very wary and smart to just any ordinary dry fly.
September 23, 2009
With flows at 775 cfs tandem bead head nymphs properly weighted and drifted through pockets and tail water will bring you fish. The Box is still the best place to fish on the upper Henry's Fork. Hoppers, Madam X with droppers or large streamers are effective too. The Ranch section is still a morning or evening deal with PMD spinners, Callibaetis, and Caddis the order of the day. Be sure to have plenty of emergers and cripples to throw at rising trout.
September 15, 2009
It's still nymph and streamer fishing in the Box Canyon with flows now around 600 csf. Most anglers are working this stretch from shore during the morning and afternoon fishing period and leaving for the Ranch section in the evening. But I would stick around and work the Canyon during the evenings looking for Caddis and PMD action on top. You can expect a Callibaetis and Trico spinner fall in the mornings with PMD's coming on in the latter afternoon in the Ranch section of the Henry's Fork.
September 4, 2009
The Box Canyon section of the Henry's Fork is probably the best section to fish on the Henry's at this time. It's currently around 775 cfs which makes it a lot easier to walk the bank and get into some really good water you couldn't get to when the water was higher. Take some nymphs and Hoppers when you go. The Ranch is still fishing slow with only early morning and evening being to most productive time to fish.
August 24, 2009
The Box Canyon area is flowing at around 1000 cfs and is probably the best section on the Henry's to fish at this time. You are going to be nymphing most of the day. Use and two bead head nymph rig with plenty of lead to get in to the bottom. Later you might want to go to a Madam X or Hopper.
August 5, 2009
The past few weeks the river has been running high and the water clarity has been off color. Fishing has been slow in the whole upper Henry's Fork area except the Ranch area. The best fishing on the Ranch has been in the evenings and early mornings. Mainly sight fishing for feeding singles or pod of trout in feeding lanes. Look for PMD'd and Flavs as your primary Mayflies and the usual Caddis. Nymphing and Terrestrials from Osborne thorough Riverside.
July 22, 2009
Right now the Box is at1600 cfs and attractor flies ( Stimulator's or Annihilators ) with a bead head dropper nymph fished along the bank should get you good results. Nymphing requires smaller nymphs at this time weighted heavy. At the Ranch you'll see Flavs in the evening and PMD's through out the day. Look for HOPPERS1
June 25, 2009
At B,ox Canyon of the Henry's Fork the rivers running around 900 cfs and the insects you will see the most will be PMD's , Golden Stones and Caddis. Unlike the Ranch area this is probably best fished with weighted nymphs in between hatches. However, A Golden Stone or Dear Hair Caddis fished dry with a bead head dropper can pay off with solid strikes.Fishing has been decent from Riverside down. Mostly nymphing and occasional PMD or attractor dry fly with a bead head dropper will do the trick.

Midge fishing at Vernon Bridge all the way to Chester Diversion Dam is the place to be according to some angler who recently fished there. When there is no Midge activity going on nymphing with large streamers with bead head droppers may work for you. Don't forget to try the Warm River to Ashton Dam section. This section is fishing quite well right now. You're going to see some midges and BWO's through out the day. Concentrate on the deeper pools with nymphs and streamers. When there is no obvious surface activity this should be you strategy.

Rainbow Trout

Brown Trout
