Well folks it that time of year, the Gallatin is in run off mode. The Belgrade and Manhattan stretches may be worth a shot, but the whole river is pretty dirty. That being said, small Skwala hatches have been seen, so you may want to try a smaller Stimi Chew Toy. With all the run off, worms and dark stonefly nymphs under an indicator, and streamers will be your best bet.
Fishing between Hebgen Lake and Ennis Lake Has been great! Midges and small BWO’s have been active on the higher sections of the rivers. As far as nymphing, flashback hare’s ears and caddis patterns behind a Pat’s Stone has been working well, along with worm’s. As far as Streamers, swinging and stripping sculpins and whitefish patterns are productive
The river has been clearing up, and weedbeds are becoming noticeable. BWO hatches have been spotted, so try throwing a parachute BWO if you see any coming off. Swinging sculpin imitations has been productive as well.
The river is extremely dirty and washed out as the Lamar Valley has begun to Melt. The Stone is not recommended, but Flashy streamers and big dark stones may be the way to go if your heart is set on it. Flows are still low, but very dirty
The Clark Fork River north of Galen is seeing some Skwalla Action on the river. Golden Stone Nymphs amd Skwalla Adult patterns work well on warm days.
Rapala countdown lures are hitting the Brown trout on the Beaverhead. Rainbow trout patterns in size 1 or 3 are the hot lure in deeper runs. Blue Wing Olive or PMD’s in size 14 or smaller are getting some surface action.
The Big Hole is high and muddy this week. Better take dark and bright colored lures to stir up the action. Size 12 0r 15 Gold Panther Martins should do the job.
The Upper Reservoir of the Missouri is seeing a lot of spawn action. Take a number, get in line, but expect to catch some 4-5 pounders. Holter and Hauser are excellent from the bank. Czech Nymphs and leech patterns are slaying the trout.
Delmo reservoir is breaking up, thinning out and accessible from Pipestone. However ice fishing is out of the question and not only about 50yds of open water for bank fishing. Bait was not having good results, but panther martins were bringing the fish.
The Jefferson can expect mud later this week
