Artificial Lure here with your Yellowstone River fishing update for Friday, May 9, 2025. After a bit of a slow start to spring, things are picking up on the Yellowstone as river flows start to settle and water temps slowly rise. Recent rain and warm weather have caused the river to swell a bit, especially upstream near Corwin, but overall conditions are stabilizing and the fishing window is looking solid for local anglers this weekend.
Expect cool mornings, with water temps rising late morning into the afternoon. This means the bite gets better as the day warms up, so there’s no rush to hit the river before sunrise unless you’re hunting for solitude. Sunrise today is around 5:57 AM, with sunset just shy of 8:43 PM, giving you plenty of daylight to work different sections.
Fishing has been good for cutthroat trout, rainbows, and mountain whitefish, with some healthy browns showing up in the mix. Trout are still hugging slower, deeper slots, so focus your efforts on wintering water with some depth and less current. Once you find a pod, slow things down and really work the run, because trout are still concentrated and not spread out just yet.
Nymphing is your best bet most days—think rubber legs, stonefly nymphs, and small beadhead droppers. The best bite has been on classic patterns like Pat’s Rubber Legs, Prince Nymphs, and smaller midges. If the weather stays stable and you see bugs popping, dry fly fishing can be solid, especially in the Yankee Jim Canyon stretch where big attractor dries can pull up hungry cutthroat.
Streamer fishing is still worth a shot, especially if the water clouds up—try olive or black buggers and keep your retrieve slow early in the day. Bait anglers should stick with nightcrawlers or cut bait in slower pools, though flies are definitely out-fishing bait with active bugs on the water.
As for hot spots, Yankee Jim Canyon is always a good bet for pocketwater and dry fly action, while the Paradise Valley stretch near Emigrant down to Livingston is a favorite for both numbers and scenery. Crowding isn’t a big problem—if you find busy water, just move up or downstream and you’ll likely find a quieter spot.
No tidal influence here, so flows are all about snowmelt and rain. Keep an eye on river levels if we get another hot day, as snowmelt can bump flows and color up the water quickly.
That’s the scoop—grab your nymph box, watch for rising fish in the afternoon, and enjoy the long Montana daylight. Good luck out there, and tight lines.
