Teton River Fishing Report

As for Teton Valley's local jewel, the Teton River, this arctic weather has all but froze most of it for now. Many of the local fly anglers that fish the Teton River have put their flyrods down and picked up the shotguns as the duck and waterfowl season has been excellent. There is a ton of public access to shoot, and it has been the most enjoyable sport for the Teton River Basin for almost two weeks. Since this year was extremely cold and early, we should expect the Teton River to break up a bit and offer more excellent winter fishing in the weeks to come. As always, feel free to contact any of our five locations for the updates on your favorite watersheds in Wester, Central and Eastern Idaho. The amazing crew at Three Rivers Ranch appreciates our customers and visitors - get out there and have fun! Want to go with a TRR guide? Give us a call and check for availability.

South Fork of the Snake River Fishing Report

Unless you have been in Mexico recently enjoying beautiful weather, you would know that mid-November has seen arctic temperatures due to the Alaskan push, and many anglers have been on the sidelines watching football and gettng ready for ski season. However, with the temperatures rising during the Thanksgiving week, many anglers are again enjoying great fishing in our Eastern Idaho rivers. The South Fork has been dropped to just over 900 cfs. Many people are still floating (and now beginning to be able to walk and wade). Nymphs, streamers, rubber-leg stonefly nymphs and zebra midges have been producing. Want to go with a TRR guide?

Henry's Fork Fishing Report

Unless you have been in Mexico recently enjoying beautiful weather, you would know that this past week has seen arctic temperatures due to the Alaskan push, and many anglers have been on the sidelines watching football and getting ready for ski season. However, with the temperatures rising during the past few days, many anglers are again enjoying great fishing in our Eastern Idaho rivers. The Henry's Fork has seen rather prosperous fishing, although the water level is very low, which is normal for this time of year. Patterns will be nymphs, streamers, midge, and BWO's. Although many fly anglers are reluctant to believe that nymphing season is here, it will be the most productive way to catch these fish, which are now honkering down close to the bottoms of these rivers where there is much less friction and the fish are able to expend less energy holding in the water column of their choice. Brown trout are now spawning. Let's respect the next generation and hold off on fishing the redds. Want to go with a TRR guide? Give us a call and check for availability.

Eastern Idaho: Mid-August Fly Fishing Report (Yes, it's good!).

Yes, it’s mid-August already.   With afternoon temperatures reaching into the mid-80’s and cool evenings dropping into the mid 40’s, it is mother nature’s perfect balance for keeping our rivers and lakes at the optimal temperatures for active fish.

Heading to the South Fork of the Snake River for a day of fishing or extending it into two days with an overnight camp trip, is well worth your time.  The water level coming from the Dam is 10300 CFS, and 5890 CFS at Lorenzo, which indicates above average water flow for this time.  (What does that mean? More water equates to optimal water temps, which equates to prime aquatic hatches, which then equates to really good DRY FLY fishing)!  You will not be disappointed on any stretch of the South Fork right now.  Fish are feeding in the riffles on PMD’s, as well as terrestrials.  The grasshoppers are finally out and they are large!  The classic hopper/dropper combination is working well, but try a twist on that and use a hopper with a pmd cripple attached and watch them choose which fly to eat!

Henry’s Fork and Teton Rivers are also both worthy of your time and attention.  Now is the time for fishing the upper Henry’s Fork with grasshopper and ant patterns. Here’s a hot tip for fishing the Railroad Ranch in the next few weeks; the fish there become accustomed to seeing flying ants often and will take your ant pattern even if you are not seeing the ants on the water.  Lower down on the Henry’s is some of our favorite water and we are seeing the big browns eat grasshoppers.  River flows are average for this time of year, with the Box Canyon a little higher than average, and much better fishing due to cooler than average water temps.

The Teton River is exploding with rises in the Teton Valley area. Brookies, Rainbows, and Cutthroat are all being caught on PMD and Caddis dry fly patterns. As you move down river, the canyon section is scenic and wild, just like the fish.  We have experienced guides to take you through this whitewater section of the Teton, fishing with grasshoppers and floating through whitewater makes it a magical day.  Even further down river, the Teton River is clear and the fish are eating grasshoppers, pmd’s, and caddis.

Ever fished for GULPERS on Hebgen lake?  If hunting for rising, cruising fish, sounds good to you, now is the time to check it out!  Bring a box full of parachute adams and nothing more.

Walk and wade spots in the area are not to be overlooked.  Often times hiring a guide means floating in the boat.  We encourage you to take a walk and wade day with our experienced guides in Yellowstone, Robinson Creek, Warm River, Falls River, to slow the pace down, stand in the water, and sight fish to wild trout, for an experience of a lifetime.

Late July Fly Fishing Report for Eastern Idaho

The Henry’s Fork continues to produce world class fishing as we enjoy these last days of July. In the canyon sections and Last Chance, you’ll want to try golden stone patterns, PMD’s and spinners, nymphing and, various stonefly patterns are also working. 

Warm River has been a wonderful spot to walk up and down with Sally’s still lingering, as well as the Golden Stone still doing its thing. From Warm River to Ashton, the fishing continues to be great, this is what we love and appreciate about this amazing river.

We have it on good authority that the lower sections of the Henry’s Fork are still doing well, with some sightings of several different caddis varieties coming in. Try Sally’s, caddis, PMD’s, golden stones. Below surface try nymphs, and hopper- dropper combos. If you haven’t already, check out this great article by senior guide, Cliff Weiss on fishing droppers.

The Teton River has finally turned on and should be spectacular throughout the upcoming weeks!  The water has lowered and cleared. Among the PMDs and Yellow Sally’s, the report we are hearing is that big foam and hopper patterns have been producing better fish as this week winds down.  Look for a water drop over the next weeks which will make the walk-n-wade scene turn to all motors forward. If you like to walk and wade, consider the tributaries of the Teton, such as Bitch Creek and Conant Creek. These sections have been equally as exciting!

On the South Fork right now from the dam to the confluence of the Henry’s Fork the fish are stacking up in the riffles. Try PMD’s, and if the fish aren’t taking that, we’re starting to see Yellow Sally’s- give them a try. In the morning and evenings, it’s caddis, caddis, caddis! Also, just a little tip, with all the food available right now, you’ll want to practice some patience.  Wait, for the fish to actually take your fly before setting the hook. That’s how you’ll get ‘em!

Henry's Fork: Fly Fishing the Salmonfly Hatch on the Snake River (& When It Will Happen).


There are few insects that create so much buzz, anticipation, and sheer excitement as the Salmonfly.  The Salmonfly is the largest stonefly in our rivers; some adults and nymphs approach 3 inches in length.  It’s not only the sheer size that makes the Salmonfly unmistakable, but it’s also the orange markings on their stomachs.


The unique thing we enjoy about our location is how the population of Stoneflies emerges on a river system as the Henry’s Fork.  Typically, Salmonflies will emerge from the furthest point downriver, and then work their way upstream.  However, due to the regular flow and temperature of Warm River, Salmonflies will emerge a few days earlier on Warm River than the lower section of the Henry’s Fork.  This gives us a good idea that the Salmonfly hatch is underway.  We can then expect the hatch to begin on the lower section of Henry’s Fork and move up river towards Three Rivers Ranch and other upper sections.


The best way to fish the Salmonfly hatch is with a drift boat.  You can cover more water and also increase your chances of finding feeding fish.  It isn’t completely out of the question to wade certain sections; however, many fish move in close to the banks to feed.  So by using a drift boat, you eliminate the chances of standing where you need to be fishing.


Fishing the Salmonfly can be very frustrating and exciting all in the same.  Breaking a rod in frustration is not uncommon.  Many trout are a bit leery of seeing an adult Salmonfly floating.  It’s like seeing a 10-pound cheeseburger.  You’ll see a trout bump the fly, swim downstream, slap it again, and still refuse your fly.  Sometimes the fish is only waiting for a twitch of your fly.  If you size your fly right, just under the size of the naturals, you’ll even see a trout deny the natural for your imitation.


The winter, spring runoff, and general weather greatly affects the Salmonfly hatch.  This is what makes the hatch so elusive for so many anglers.  On a typical year, you can expect the Salmonflys to begin emerging in late May to Early June.  Again, that depends on many factors, but it’s a good estimate.


Fishing the Salmonfly hatch on the Henry’s Fork is something every angler needs to experience.  It’s challenging, elusive, and very worthwhile.


If you are interested in fishing the Salmonfly hatch, give us a call (800) 360-9051or This email address is being protected from spambots. You need JavaScript enabled to view it. starting around May 15th to check on the hatch.  Be sure to have your bags packed and sitting by the door!

2014 - Henry's Fork Salmon Fly Hatch Update:  We're expecting the hatch to begin in about 3 weeks (towards the end of May 2014)!  About the same time as our Teton Valley Fly Fishing Festival!  Mark your calendar!

 Not much has changed in the past couple of weeks as far as fishing conditions go. Although all rivers are still being productive, things have been a little tough. Check out our last post as far as what flies to use right now. But be ready. As the weather cools and the water temperatures begin to drop, look for the emergence of Blue-winged Olives and Mahogany Duns.

TRR guide Rocky Elliott shows off his latest catch.



Idaho Fly Fishing Report for Henry's Fork, South Fork, & Teton River


Are you ready for these Dog Days of summer to end? Let's be honest. The past few weeks of fishing have been a little difficult, although always rewarding. We're happy to report things are picking up everywhere and fishing has been much more productive. Take note: a Hopper Dropper seems to be working pretty much anywhere right now. That beautiful hybrid (pictured below) caught by Susan, with Three Rivers Ranch guide BJ Gerhart, was caught on a hopper. Sweet!

Here's what to expect and what to use as you head out for that perfect catch.

Railroad Ranch - The ranch has been fishing really well. Always very technical, use long 12-14 ft. leaders and light 5/6X tippet. Try trico's in the morning, little black ants mid day, Hoppers in the afternoon, mahogany from morning to early afternoon, callibaetis in the morning and early afternoon and throw beetles to the fish who just won't eat anything!

Box Canyon - Fishing pretty well with 16-22 inch rainbows being caught and released . Right now it's pretty much a nymph game as the water is a little off color. Try small Mayfly nymphs or a Hopper Dropper combo.

Henry's Fork of the Snake - Warm River to Ashton - Why do we love the Henry's Fork? Simple. It fishes well. Try dry droppers with a variety of nymphs. Or only nymph it. No major hatches going on but it's still fishing really well.

Henry's Fork - Lower Section (Below Ashton) - The hot days of summer have led to this section being very mossy with lots of free floating grass, very slow. Try a Hopper Dropper combo.

Teton River - Has been fishing pretty good. Try hoppers, ants, trico's.

South Fork of the Snake River - has been picking up as the water levels are dropping. Palisades to Spring Creek is fishing pretty good overall. Use a Hopper Dropper set up. Mornings and evenings are the best time to hit this section. In The Canyon - Same. Hopper Dropper set up. From Byington to Menan - Getting more productive. Try Hoppers on the grassy banks. Fish are on the ripples.

Teton Basin – Technical fishing. Try PMD's & trico's. Also try small hoppers - the smaller the better, ants and beetles.

For the best selection of flies, including Hopper Dropper combos and gear, stop into one of our four fly shops and talk to one of our expert guides who are always happy to help you. Fishing the Henry's Fork and need a vehicle shuttle? We got ya covered! Call to make a reservation for your Henry's Fork shuttle now. (208) 652-3008

Mid July - Idaho Fly Fishing Report

Box Canyon continues to fish well. We recommend trying a double nymph set up like a Golden Stone and dropping a Red Copper John. Drakes are about done, but we're starting to see a few Stone Flies. Going lower? Use Caddis, PMD's or Drakes. The Railroad Ranch is fishing really well. We've had quite a few veteran anglers tell us it's fishing (in their humble opinion) like it did 20 years ago. Lots of fish for your patient, determined angler. Try Caddis and Brown Drakes.

The Upper Section of the Henry's Fork is still generating great fishing. Try Golden Chernobyl and nymphs. Stop in to one of our fly shops for current sizes and color patterns or give us a call. Clients yesterday netted 25-30 fish by noon!

Lower Henry's Fork try PMD's, Green Drake, Caddis and Golden Stones.

The Teton, in the basin near Victor and Driggs has trout rising every evening to the Caddis hatch and PMD's.

The Teton River in the upper valley has been a little hit or miss but we are finally into the dry fly season. Try Yellow Sally's and PMD's – be on the lookout with warm temps for grasshoppers to pick up by end of the month.

The South Fork of the Snake – Fishing well! On the banks try Golden Stones or stop into one of our fly shop's and try Head Guide, Doug Gibson's Michigan Hopper. Also try Chubby Chernobyl's. In the ripples we're seeing them rise to PMD's and first thing in the morning and evening try Caddis and flying ants. The water temp has been around 60 degrees, which is a good temp for insects. Once it gets a little warmer we'll see those prime hatches take off.

Perhaps one of the best ways to fish the South Fork of the Snake is with an experienced, veteran Three River Ranch guide! The canyon section is by far one of my favorite floats. Those who have yet to see or experience it, should put it on your summer bucket list.

Idaho Fly Fishing Report: Henry's Fork, Teton River, & South Fork of the Snake River.

According to the calendar, summer has officially begun! Here's to great weather, big hungry trout and enjoying those late evening summer hatches! And here's what to expect while out on the river: 

Henry's Fork Fly Fishing Report:

Box Canyon still has a few Golden Stones, but nymphing still remains good or running dry hoppers. The Golden Stones are out in Cardiac Canyon below Mesa Falls; you can also try Mayfly nymphs, Copper John's and Pheasant tail nymphs. 

Check out our recent blog on the record number of rainbow trout in Box Canyon. More than any other year since the 1970's!  Also,the Railroad Ranch opened last weekend and Green Drakes are starting to come off in good numbers.

Warm River to Ashton – Golden Stones are out and also a bunch caddis.

Lower section – Grey and Green Drakes, lots of caddis and few PMD’s. At this point the fish are a little more picky having been worked over a bit this spring season, but they're still biting.

Teton River Fly Fishing Report:

The Teton River has cleared and is fishing well! Try Big Bead Head Copper Johns and Pheasant Tails, Salmon flies, Green Drakes and streamers. In the evening try Caddis, Lots of Cutthroats.

South Fork of the Snake Fly Fishing Report:

The South Fork has exploded and is fishing fantastic! Our guides are reporting lots of fat, hungry fish, primarily browns anywhere between 16-18 inches. Although there are plenty of rainbows and cutthroat biting too. Try Salmon Fly adults,Green Drakes, PMD's, Caddis, Pink Albert's & Blue Wing Olives for dry flies. Also try rubber leg Stone Fly nymphs.

Lonnie Allen Fly Fishing the Teton River







East Idaho Fly Fishing Report: Henry's Fork, Teton River, & South Fork of the Snake River

 What’s Happening Now on the Henry' Fork of the Snake River?

The Henry’s Fork is fishing really well! We’re in between hatches as the Salmon flies were a bit early this year and just finished up. They’re currently biting Caddis & PMD’s and a few Golden Stones.  The Golden stones should be picking up soon, so watch out for them.  We’ve been catching a lot of nice size fish so far, and plenty of them!  Last week one client caught a 27 inch Brown on the lower section.  Sweet!

What’s Up Next?

As we enjoy the Golden Stones picking up, we will also eagerly anticipate the arrival of the Green Drake’s. Within the next week or so, we believe you’ll start to see them come off in good numbers and then progressively increase in numbers on the lower Henry’s Fork. About the same time this is happening watch for the Brown Drake’s to start along the upper Henry’s Fork sections going north. We’ve also seen some Yellow Sally’s flying around, so watch for those too as they’ll pick up shortly.  Opening day for the Railroad Ranch in Harriman State Park is June 15. Game on!

Henry's Fork Shuttle Service >

How About the Teton River?

The Teton River continues to come down and is clearing up, should be fishing well soon. We’ll be looking for the Golden Stone’s shortly and then from there they will move on to Caddis and Terrestrials (grasshoppers, beetles, ants) as the summer progresses. 

<Teton River Shuttle Service>

What’s Happening Right Now on the South Fork of the Snake?

The South Fork is fishing well right now with nymphs and streamers. Visibility and flows are good, bugs haven’t hatched yet, as they are still lowering the water. Salmon flies will be a little earlier this year than in years past.  We anticipate the lower river (anything below Twin Bridges) seeing Salmon Flies by the end of June through first of July.


What’s Up Next for the South Fork?

All summer long watch for – Mayflies & Caddis on the South Fork.  Toward the end of July and into August watch for Grasshopper’s to start picking up on the South Fork.  Also in July watch for hatches of PMD’s and Caddis.

The South Fork has a population of well over 5,177 fish per mile. Wild cutthroats averaging 14-16 inches, as well as rainbows and hybrids can be found. You will also find brown trout that can grow much larger than 10 pounds.  Although the South Fork is best known for its dry-fly fishing and steamer fishing, casting big flies under-cut banks, or dead drifting a bead head nymph along the numerous gravel bars can be very effective and exciting!

17,000 Trout in the Box Canyon Section of the Henry's Fork of the Snake River.

Recent research by the Henry’s Fork Foundation and Idaho Fish and Game biologists shows that there are currently more Rainbow trout in the Box Canyon stretch of the Henry’s Fork then there has been since the 1970’s. A few major factors they believe contribute to the increase of Rainbows is due to a large number of two-year old fish spawned in 2011, the increased water flow from the Island Park Dam from the 2011-2012 winter, and possibly due to the increased fish production from the Buffalo River. Whatever the case, biologists believe there are 6,200 fish per mile, plus or minus 500.

Stop in to one of our conveniently located fly shops in either Island Park or Ashton, Idaho to get hooked up with the right flies to tackle the Box.  Right now you’ll want to have some Golden Stones, Green Drakes, Rubber Legs and Caddis. If you’re interested in a guided fishing trip through the canyon section you can reserve your guided fly fishing trip NOW or call the fly shop. (208) 652-3008 in Ashton or (208) 558-7501 in Island Park.

Henry's Fork Fishing Report - Mid May

If you're planning on Fly Fishing Idaho, now it's a great time to do so.  Your best bet for fly selection on the Henry's Fork of the Snake River is Caddis, March Browns, Streamers, & Rubberlegs.  

Spring runoff is here and we are seeing dirty water conditions.  As temperatures rise, expect waters to get higher & slightly more turbid.

Many fly fisherman in the area are starting to talk about the Henry's Fork Salmon Fly Hatch.  If you can make it to the area during the peak of the hatch, it's something to check off your life-list (fishing wise).  The Henry's Fork Salmon Flies are getting closer by the day.  We are expecting the temperatures to rise in the next two weeks, which will affect the temperature of the water.  As the water temperature rises, we will start seeing the hatch emerge from the lower sections of the Henry's Fork and move up river, towards Warm River & Island Park. 

Overall, fishing has been good lately.  The best news is that the fishing here in East Idaho is only going to get better.

Stop by our Ashton Fly Shop to see our new product lines:  Patagonia, Echo, Rio, William & Joseph, & Korkers.  We also started a new Henry's Fork Shuttle Service as well.  If you're looking for a River Shuttle on the Henry's Fork, Teton River, or the Fall River give us a call (800) 360-9051 to book your East Idaho River Shuttle.
