Big Hole River 7/9/26

• Awesome! Good flows, lots of bugs, fat happy fish.  Sallies in the afternoon, pmds, caddis in the mornings.  

Beaverhead River 7/9/26

• Flows are up and the river is fishing again.  A few weeds as you get below henneberry but they are manageable.  Pmds still there and some sallies.  

Big Hole River 7/5/26

• Awesome!  Lots of dry fly opportunites out there.  Sallies, pmds and caddis, lots of water oh yeah.  Nymphing rubberlegs, san juan worms, lightning bugs, copper johns all good.  

Beaverhead River 7/5/26

• Fishing great especially on foot, flows are super low but should hopefully change as they start to irrigate again.  Pmds are still heavy, try getting smaller size 18 slipt backs, barrs emergers and sally nymphs 

Big Hole River 7/1/26

• Lots of water yipeee, should keep the system healthy and going for awhile.  Although high its still fishing.  Streamer guys are having fun, nymph em up with a san juan, prince, rubberlegs and lightning bugs

Beaverhead River 7/1/26

• With the recent much needed rain they have really lowered the beaverhead to save some water.  As of this morning floating is a challenge but still very doable.  Look for the fish in the deeper runs and pockets, pmds still amazing when the clouds come over.

Beaverhead River 6/26/26

• On fire right now! Pmds are out in force, lots of heads up for the patient fisherman, nymphing remains the most productive.  San juan worm picking up fish but a great attention getter follow that with a barrs emerger, split back or phase II or crack back pmd.  

Big Hole River 6/26/26

• Still fishing great especially 7am to 2 pm.  Bugs are still flying, sallies in the early afternoon, pmds and caddis in the mornings and evenings.

Big Hole River 6/22/26

• Although the flows have been dropping its buggy out there and a dry fly mecca if desired. Pmds in the am mixed with caddis, occasional golden and olive stone still fluttering and lots of sallies.  

Beaverhead River 6/22/26

• Pmds, pmds, pmds. Lots of bugs getting going out there, still hard to find some risers but they are there.  Nymphing has been fantastic.  Split backs, barrs and a few secrets.

Big Hole River 6/17/26

• Still some goldens here and there and lots of pmds and yellow sallies are out.  Early morning to noon then later in the evening best for dries unless its cloudy.  Split backs, barrs emergers, san juan, rubberlegs, sunkist and lightning bugs should do just fine 

Beaverhead River 6/17/26

• The pmds are here and the fishing is fantastic.  Grab your favorite emrgers and nymphs and have some fun.  Stop in and we will show you some of our go to patterns.  They are still spotty eating them on top but there have been a few pods here and there.

Big Hole River 6/11/26

• Salmon fly hatch is all but over.  There are still a few in the canyon and up higher on the river.  Look out for goldens! Pmds are out in force and when the fish get full on all that big stuff a pmd is a welcome snack 

Beaverhead River 6/11/26

• Fishing as good as it gets, the pmds have arrived and yesterday in good numbers.  Saw a few fish looking but it will only get better soon.  Split back pmds, barrs emerger, tungsten pahse II along with the usuals san juans and scuds will get the job done 

Beaverhead River 6/8/26

• Fishing great all the way to town.  Scuds, midges up top, san juans, bwo stuff, pmd crawlers.  The pmds are close!!! There has been the early birds flying around from 10-2, the dry fly rods are rigged and ready just in case 

Big Hole River 6/8/26

• Salmon flies are still going strong river wide, they are getting full in some places but with the clouds lately it has been some of the best dry fly fishing we have experienced in quite a while 

Big Hole River 6/3/26

• Salmon flies have popped up and down the river. Time to get out there and throw some big bugs its not going to last too long this year.  Lots of pmds as well, if they are full on the big stuff dont be afraid to go small. 

Beaverhead River 5/29/26

• our guides have had some awesome fishing on the river the last few days.  Might have seen a pmd or two flying around yesterday but it will be a little bit.  Fish are still on scuds, midges and bwo’s with great fishing morning to night.  Check out this nice brown from yesterday.  

Big Hole River 5/29/26

• Stone flies are crawling and saw a few flying on the lower river, time to come in and stock up on the big bugs.  The weather this weekend will probably delay the salmon fly hatch but get ready next week!

Beaverhead River 5/26/26

• Farely fantastic so far this year is the best discricption I guess.  Fewer monsters in the river but I would say numbers are way up.  Scuds, bwo nymphs, midges in the am and some caddis down low.  

Big Hole River 5/26/26

• The river is fishing great from top to bottom.  More clouds of caddis and eager fish the farther you head up river.  Fish are really keying in on rubberlegs as the stone flies start crawling and getting close to the banks.  Salmon flies not too far off.  

Beaverhead River 5/20/26

• Off to a great start this spring, fish look healthy and happy.  Scuds, midges, san juan, bwo nymphs are all you need. 

Big Hole River 5/20/26

• The entire river is in great shape again but canyon down still remains a bit cloudy but clearing everyday.  Upper river fished awesome yesterday.  San juan worm, prince nymph, rubberlegs, lightining bugs and saw some caddis fluittering in the afternoon. 

Beaverhead River 5/17/26

• Opening weekend was a good one! Although there was a crowd out there the fish are healthy and eager at the moment.  Same bugs apply scuds, midges, bwo nymphs, san juan. 

Big Hole River 5/17/26

• Still a bit dirty and off color in the canyon and downstream.  Don’t be afraid to head up river where there is some more clarity.  San juan worms to a caddis pupa, prince or lightning bug should produce and slow strip some big bugs in yellow or black.

Beaverhead River 5/15/26

• Opening day forecast.  Big hungry fish await!  Remember opening weekend can get a bit busy so leave some room for each other out there.  Scuds, midges, san juans, bwo nymphs should be all the combos you need out there.  Stop in and we’ll show you what we would have on!

Beaverhead River 5/12/26

• Opening day for the upper river is this Saturday the 16th.  Stop in and make sure you have the right bugs and check out the latest river forecast and tips.  

Big Hole River 5/12/26

• A bit tingy from Divide down but don’t shy away from the upper river. Throw some junk like a peanut envy or scupzilla. Worm with a lightning bug or prince should be just fine as well.  Caddis will still be going strong so if it doenst get too dirty should be awesome.

Happy mother’s day weekend to all the wonderful mothers out there! Grab some caddis and hit the water!

Big hole River 5/7/26

• Flows have stabilized after a little bump and should remain that way until some of this warmer weather arrives later this week/weekend.  Caddis caddis caddis with some may flies in the am.  Now is the time the mothers day hatch is on!!  Come check out the latest patterns to make your day a successful one 

Beaverhead River 5/7/26

• They have started to release some minor flows and the river is now floatable again.  Scuds, san juans, bwo and some caddis down lower.  Don’t be shy to throw some streamers too the water temp is prime.  Try some scupzillas in olive or black or the peanut envy in black/olive/brown.  

Big Hole River 5/4/26

• Currently the big hole is fishing some of the best I’ve seen this time of year in a long time.  Morning hatches of mayflies and the caddis have started!!  When the clouds hit have that dry fly rod ready to go. They are primarily on the lower river but should go river wide this week with the nice temps. Stop in to get the latest go to patterns.  

Big Hole River 4/30/26

• The river is off to a great start with some wonderful spring flows that are holding steady.  We received quit a bit of much needed snow so it should help out in the long run.  No need to get scientific out there right now, rubberlegs, san juan, prince and some bwo stuff is all you need.  

Beaverhead River 4/30/26

• Update on the coming flows from the reservoir.  We can anticipate a slight increase over the next couple of weeks. A lot depends on the weather but hopefully more floatable soon.  Fishing is still good with the standard stuff, scuds, midges, bwo nymphs and san juans.

Big Hole River 4/20/26

• Flows and fishing remain great!  Nymphing a san juan, pats rubberlegs to a lightning bug, bwo nymph or standard prince will produce plenty.  Still a few sqwallas and some bwo action on top.  

Big Hole River 4/10/26

• Fishing awesome thats all that needs to be said.  Flows have leveled out and clarit is wonderful. Slow stripping streamers, sqwallas on top down low, nymphing rubberlegs, prince nymphs, and blue wing olive nymphs producing.  

Beaverhead River 4/10/26

• great fishing but still low flows and stay sneaky, same bugs but some great bwo hatches on cloudy days.

Beaverhead River 3/30/26

• Still at winter flows so sneak yourself into those holes but the fishing has been fantastic, watch out for the occasional rainbow redd below pipe organ.  Blue wing olives on cloudy days otherwise nymphing the usuals, zebra midge, baetis, scuds and san juans.  

Big Hole River 3/30/26

• Just 2 days away from opening and conditions are looking great, Sqwallas on the surface and some great nymphing action.  Call today to book your April trips.  

Big Hole River 3/12/26

• Opening April 1st, only a few weeks away!!  The mountains are getting pounding right now for the next few days which should really help the snow pack.  Lower river sqwalla outlook looks good, can’t wait to get out there and throw some early season big bugs.  

Beaverhead River 3/12/26

• Some of the fish have moved back into areas below pipe organ and the fishing has been fantastic.  Clouds and some nice weather we were able to raise a few on blue wing olives.  

Beaverhead River 2/9/26

• The weather has given us plenty of nice fishing days this winter.  The open section between pipe organ and barretts has been hit and miss.  Sunny days get sneaky, river is low and clear they spoke easily.  Looking into a lot of the holes, I think a lot of fish moved up river this fall to spawn and have remained there.  Try scuds, midges, and baetis nymphs on the nicer days 

Beaverhead River 12/8/25

• Did some quick fishing the other day below pipe organ and caught some great fish on a scud/baetis combo.  Poked a couple on the surface with a brief blue wing olive hatch as well.  Worth getting out there and enjoying these beautiful early winter days.  Remember the Beaverhead is only open between pipe organ and barretts.  

Jefferson River 12/8/25

• On the non windy and warmer days the streamer fishing has been pretty fun, keep the strips slow and long. 

We will be open for small business Saturday November 29th, stop in and stock up for Christmas!!  9am-3pm.

Beaverhead River 11/18/25

• The river between pipe organ and barretts is the only open section and fishing very well with all the nice weather we have been having.  Try nymphing some blue wing olive nymphs leading with a scud or san juan.  For the patient angler there was a decent olive hatch with a few tricky heads poking out!!

Jefferson River 9/13/25

• Fish are still slamming the hopper on certain banks, hanging a tnt jig produces more.  Don’t shy away from nymphing the deeper runs

Beaverhead River 9/13/25

• Weedy and off color but fishing ok in the right stretches.  Some areas around town and mid river have been the best.  Hopper dropper the way to go, stop in and see whats been working.

Jefferson River 9/5/25

• We have been on the Jeff for the last few days since it reopened and have had some great action.  Hopper dropper with some nice dry eats, streamers in the am and nymphing the deep runs.  

Beaverhead River 9/5/25

• Flows are dropping which has made wade fishing easy and fun.  Fish are still eating crane flies, and nymphing is good but still need to keep the flies clean from moss and grass 

Big Hole River 8/26/25

• closed entirely until further notice- hopefully some rains in the next few days and some conscious decisions to reopen there after 

Beaverhead River 8/26/25

• A bit weedy and off color but try a hopper dropper especially on the coming cloudy days and throw those crane flies there has been some awesome action 

Big Hole River 8/20/25

• Fishing awesome until 2.  Tricos are still around but the hatch is lasting a little shorter, 2 hours maybe, 9-11 the best.  Try a hopper dropper and find the deep runs.  

Big Hole River 8/16/25

• Remains under hoot owl so no fishing after 2pm.  Tricos are still strong from 9-11 ish and the nymphing has been great.  Lets hope water users can conserve a little so it doesnt have to shut down and we can all enjoy the resource.  Longer colder nights have produced some great water temps especially in the morning and the fish are responding to that.  

Beaverhead River 8/16/25

• The river is still very grassy but if flies kept clean it has been great. The early bird can have a blast on crane flies, and the hopper bite has been good.

Big Hole River 8/5/25

• Still under hoot owl restrictions so you have to be done by 2, however it is still fishing great!!  Tricos river wide and spruce moths on the upper stretches.  Hopper dropper getting better each day, and a rubberleg through the deeper fast runs as the nocturnal stones are crawling around.  

Beaverhead River 8/5/25

• Crane flies are out and what a blast.  River clarity comes and goes still with storms churning up the lake and try and keep those flies weed free.  Nymping still productive with san juans and pmd crawlers, baetis stuff.  Don’t shy away from a hopper they are looking for them.

Big Hole River 8/1/25

• Tricos in clouds at times, 9-11ish.  Never been better, remains under hoot owl so closed 2 om on.  

Beaverhead River 8/1/25

Beaverhead River 7/20/25

Big Hole River 7/20/25

• The entire river has been under hoot owl restrictions so no fishing from 2 pm to midnight, that being said the fishing the last few days has been fantastic especially from 8-1pm.  Tricos have started and the dry fly fishing has been really fun

Beaverhead River 7/9/25

• Pmd’s and Sallies are out and a few fish sippin away.  Look hard but they can be found and caught.  Nymphing has been the most productive but nice to switch up when the opportunity comes.  

Big Hole River 7/9/25

• Get out early and off by the early afternoon, water temps are warming but the fishing remains great!!  Still good hatches of sallies, time to start the hopper drop as well.

Beaverhead River 7/4/25

• The river is at its best right now, pmds from 9-12 and sallies intermixed 11-2.  Find the dry eaters and nymph the rest.  San juans, pmd emergers and sallie nymphs working the best

Big Hole River 7/1/25

• flows are dropping but the fishing remains absolutely amazing especially between 7-11 in the morning.  Bright sun and heat are getting to them in the afternoon but still good hatches of pmds and sallies.

Big Hole River 6/27/25

• This season has been one to remember so far, there hasnt been a more consistant dry fly bite in quite some time.  Caddis in the am, pmds and sallies in the early afternoon!!

Beaverhead River 6/27/25

• The pmd’s have arrived in masses and fish are starting to sip when you find them.  Nymphing is still the best, flows have settled down and the reservoir has turned some color so the fish can’t see us as well

Big Hole River 6/22/25

• Rain and snow today is bumping the flow on the river which is awesome.  For the dry fly angler caddis and pmds are going strong with some afternoon sallies.  Some big fish in the system this year and all looking fat and happy.  Underneath try some pmd nymphs, rubberleg stones, caddis emergers and dont be afraid of the shallow riffles.  

Beaverhead 6/22/25

• A little snow, a little rain this morning so all good in Montana.  Pmds are showing themselves more and more everyday, they should be looking up very soon.  Nymphing still the way to go with scuds, pmd stuff, and san juans.

Big Hole River 6/18/25

• The river continues to impress us both in abundance and size of the average fish this year.  All seem to be extremely healthy and have good weight on them. Sallies, PMD’s and caddies are around for the dry fly peeps, stone fly nymphs, pmd split backs and sallie nymphs are our top producers underneath.  

Beaverhead River 6/18/25

• Flows have dropped and hellooooo PMD’s. Although not a ton of dries yet, lots of crawlers and the fish are starting to key in on them a bit more.

Big Hole River 6/15/25

• The Salmon flies have come and gone but still seeing sporadic fliers along with goldens and sallies have started in places.  The fish on the middle and lower stretches have started to eat again after the salmon fly gorge.  Rubberlegs, caddis emergers, pmd nymphs the way to go.

Beaverhead River 6/15/25

• Fishing has really started to heat up, the fish are responding to steady flows and the emergence of a few pmds. Nymphing with san juans, split back pmd, baetis, and scuds are still the top producers.

Big Hole 6/10/25

• Salmon flies are still river wide from melrose all the way up to fishtrap.  The fish are getting plump but still smacking the big bugs in places.  Switch to pmd nymphs and caddis emergers when the fishing slows down with salmon flies

Beaverhead River 6/10/25

• Flows are still fluctuating but the insect life is picking up with mayfly crawlers and scuds.  Split backs, san juans, pyscho mays will do the trick.  

Beaverhead River 6/6/25

• Flows have leveled off and the fish are starting to eat more consistently all day.  Pmd crawlers, baetis, scuds still abound.  

Big Hole River 6/6/25

• Salmon Flies!!! Grab the big bugs and have some fun, we are seeing them river wide but concentrated canyon down.

Big Hole River 6/3/25

• What can we say but consistent!!!  We saw a few fluttering salmon fly early risers to the party but the hatch is still right around the corner will keep you updated.  Still good numbers of caddis and some pmd’s on the upper river 

Beaverhead River 6/3/25

• Flows still fluctuating, patience is the game.  Fishing hot one minute, guessing the next but keep those bugs rolling the flows will level out at some point.  San juans, baetis, midges and scuds still producing.

Beaverhead River 5/26/25

• Flows have been flucuating slightly and so has the fishing, hot one minute and scratching the next, by the end of the day still lots of fish and as always on the Beaverhead some beauties.  Scuds, Baetis, san juans, and midges still the top producers.  

Big Hole River 5/26/25

• The river remains in great shape before the next surge of snowmelt in the coming days, caddis are abundant and so are the fish, on the right days the dry fly fishing has been some of the best I’ve seen.

Beaverhead River 5/20/25

• What a crazy opening weekend, the faithful were out with their headlamps before sunrise staking out their favorite spots.  Flows remain low to save water but fishing is great.  Scuds, midges, baetis nymphs, and san juans will get the job done!!
