SW Montana Fishing Report – Late May/Early June

Welcome to the latest edition of the TOTF Fly Fishing Newsletter! As the weather warms up and the rivers come alive, it’s time to grab your gear and embark on exciting angling adventures in the beautiful Bozeman area. In this edition, we bring you the most recent updates, tips, and a new section on things to do in and around Bozeman to help you make the most of your trip to beautiful SW Montana. So, let’s dive right in!

Spring has sprung here in SW Montana, and the surrounding landscape is greener. The run-off is in full swing. The season’s snowpack of >130% is showing itself, with the flows a bit higher than last year. Generally, check destinations before heading out. Rivers that are not dam-controlled will be slightly angry regarding flow and clarity. As the run-off increases, tailwaters, spring creeks, and lakes are the best places to go. Temperatures are seasonally a bit cooler, warming in the afternoons, and overnights are still low enough to keep the water on the cooler side.  

Check with us for the latest conditions around your expected trip—more below for each river destination.

Fishing Report

Madison River 

The run-off has begun on the Madison, and flows are higher than usual for this time of year. However, the fishing from Quake Lake to Palisades FAS is still fair to good. The West Fork is bringing in muddy water. The water on the Madison from Quake Lake to the Palisades fishing access site will be off-color, but don’t let that intimidate you. If you are fishing below the West Fork of the Madison, you will be confined to the east side of the river and the center down to Palisades FAS. 

Starting on May 27th, NorthWestern Energy increased flows out of Hebgen Lake to assist in flushing the fine silt in the gravel beds to improve the spawning areas. This Madison River Flushing Flow Program is designed to augment natural river flows with surplus water in good snowpack years to correspond with the West Fork and other tributaries to match the flows with clearer water. The flow increase is scheduled to continue throughout May. Conditions dictate fishing in the slower water and buckets below the surface; patterns of stoneflies, baetis, caddis, and worms are all producing well.

The lower Madison is doing well. The snow melt has Cherry Creek doing its thing and adding color to the river. The fishing below the Beartrap Canyon from Warmsprings downriver has been hit or miss. River flows are up, and clarity is not an issue. 

The Mother’s Day Caddis hatch came off on schedule but was shut down by the colder-than-average temperatures for this time of year. We are also seeing some March Browns, Blue Winged Olives, Skwalas, Midges, and a few PMD’s.

5/31/23 CFS at Kirby Gauging Station 3,170 and dropping. Water temperature at 3:45 pm MST, 51° F

Missouri River 

The jet boat section below Hauser Dam near Beaver Creek or the drift boat section below Holter Lake is fishing very well. These rainbows are feisty and acrobatic and are putting on a good show. On the Mighty Mo, the most common nymphs are Baetis, Midges, Sow Bugs, and Scuds. Suckers are in full spawn, and trout are slurping up any of their yellow or green eggs as they wash downriver. On overcast days, we see Baetis hatching, and if the wind isn’t blowing, you can find heads up feeding on them. We are starting to see a few PMD’s (Pale Morning Duns)- stay tuned as this hatch is about to get really good.

5/31/23 CFS below Hauser Dam – 8,150. CFS Below Holter Dam – 8,180. Water temperature at 3: 45 pm MST, 56° F

Yellowstone River

The Stone is very angry and not fishable. Flows are 1.5x to 2x the highest flow we deem safe to fish. With the snowpack and current conditions, we may have to wait until the middle-late June before we can get a boat on the water.

5/31/23 CFS at Livingston gauging station – 17,000. Water temperature at 3:45 pm MST, 52° F

Hebgen Lake 

The lake is fishing well. Start and finish your day fishing under a strike indicator with a Leech and a Chironomid nymph. Short leash, about 3′ from the indicator to the bottom fly. There is no rush to get on the water as the water temperatures are still very cold. Late afternoons and evenings have been more productive if the wind stays at bay. Another great technique this time of year is casting a crawfish pattern to the bank, letting it sink, and slowly retrieving it back to you. When fishing at Hebgen Lake, location is paramount. Our guides use motorboats, an advantage over a drift boat or wade fishing. This allows us to safely motor to different sections of the lake to find the feeding fish and is not as dangerous as being in a drift boat when the wind and waves pick up.

Hebgen Lake Montana


  • Icecream Cone, red – size 16-12
  • Jumbo JUJU Chironomid, red or zebra – size 16-12


  • Near Nuff Crayfish, brown or olive – size 6

As always – check ahead of the weather conditions and flows to enjoy a safe and productive time on the water. You can always consult with us here at TOTF – for guided trips or if you just want to go it alone. We have a vast stable of seasoned guides that provide us with real-time information on the waters in the area. 

Yellowstone National Park

The opening day of the fishing season in YNP is 5/27/23. October 31 is the last day of the fishing season in YNP. Unlike Montana, YNP has fishing hours from sunrise to sunset. 

Opening day in the Park always coincides with run-off. However, some locations will fish well during this high-water period. We will mainly focus on the west side—rivers like the Firehole, Gallatin, and Gibbon Rivers. Check in with us for current conditions and be safe while these rivers are high.

A friendly reminder that the Park does not allow felt bottom wading boots.

You can purchase your YNP fishing permit online; no need to wait for a licensing agent to open up to get you on the water. Click HERE to buy online.

A reminder: All of your guided fishing trips on the Northeast corner of YNP are two-day minimum. This means your guide will meet you at a convenient location for you and the guide. For any trips on the West side of YNP, we will accommodate single-day trips.
