Runoff season is officially packing its bags, and the crew down at the Lightweight Fly Shop in Stevensville, Montana reports that our local rivers are finally rolling out the red carpet. We are sliding into that glorious early-summer sweet spot where the water volume is perfectly manageable, the fish are looking up, and the bug hatches are firing on all cylinders. There is a slight catch, though: Mother Nature is cranking the thermostat up toward 90°F by midweek. To keep the trout happy and your drag screaming, you’ll want to behave like a morning person. Set your alarm for an 8:00 a.m. launch, pack a stream thermometer, and plan to wrap things up by 2:00 p.m. before the midday sun turns the rivers into a lukewarm bath.
When it comes to picking your playground this week, Lightweight Fly Shop notes that the local waters are offering a “choose your own adventure” menu based entirely on your fishing vibe:
- The Bitterroot: Your ultra-reliable, crowd-pleasing MVP offering the most consistent mix of dry-fly and nymph fishing.
- The Blackfoot: For the heavy-hitter floaters chasing big foam bugs, strong banks, and a shot at a legendary trout.
- The Clark Fork: A patient angler’s paradise featuring massive water and highly rewarding dry-fly windows.
- Rock Creek: The ultimate wading buffet, currently transitioning beautifully from salmonflies to golden stones and drakes.
- The West Fork: The clean, clear, and technical sanctuary for anyone craving smaller-water precision and picky fish.
To crack the code, ditch the clunky spring rigs and lean heavily into the art of the dry-dropper setup. The chaotic salmonfly craze is mostly fading into the mountain headwaters, leaving the stage wide open for Golden Stones, PMDs, Yellow Sallies, and Green Drakes to steal the show. Slap a size 6-10 foam stonefly tight to the shaded banks or drift delicate mayflies through the slow-moving foam lines. If the forecast holds true and we get a few cloudy thunderstorms around Friday, don’t head for the truck—the shop folks point out that gloomy weather is actually a golden ticket for epic afternoon Green Drake hatches and aggressive streamer strikes. Keep your casts tight, your beer cold, and your eyes on the water temps!
