Good morning anglers, Artificial Lure here with your Yellowstone River report for Saturday, August 30th, 2025.
Sunrise broke over the Absarokas at 6:37 AM this morning, and you can expect sunset around 8:05 PM this evening. The weather out here is classic late-summer Montana—cooler nights have kept water temps in check, hovering between 61 and 67 degrees, but daytime highs will flirt with the 80s. High haze and a bit of smoke still linger, so keep your eye on changing conditions and always check those local fire restrictions.
No tides to worry about—this is pure Rocky Mountain freestone action. Streamflows are running a bit low for the time of year, right around 1,580 CFS at Livingston as reported by the Yellowstone Angler. Lower flows and warmer afternoons mean you’ll want to target that prime morning window and maybe the last magic hour before dusk. Be respectful out there—lots of folks are taking advantage of this good weather, so give each other some space and keep it friendly.
Fishing has been lively, especially early and late, with the best trout action in the cool, fast riffles and midriver runs. The big story this week: hoppers, ants, and a few sneaky beetle patterns. According to local guides on Montana Angler and recent catches photographed by regulars like Ashby Bell and Jackson Bruff, cutthroat, rainbows, and a few browns have all come to hand. Hopper patterns in peach, pink, or tan—Morrish, Grand, Sweetgrass, Thunderthighs, and Fancypants—sizes 8 to 14 are must-haves. If the fish start refusing, switch to a smaller beetle or floating ant and you’re back in business.
Below the surface, nymphers are scoring solidly with rubberlegs in black and coffee, bead-head princes, Euro nymphs, and variants like the Lil Spanker and Duracell Bomb. Drift those along bankside structure in the morning, or target the heads of riffles as the day warms up. For those chasing a bigger target, streamer fishing right at dawn or in that dusky light has been very productive. The Coffee Sparkle Minnow, Black Leadeye, and Slick Willie in black, olive, or natural have pulled some nice fish from deeper runs and side channels, especially below Pine Creek and Carter's Bridge.
Recent stats from the Yellowstone Angler and Montana Angler reports show several anglers landing cutthroat up to 17 inches, rainbows to nearly 19, and chunky browns pushing 20 if you cover enough water. The hopper bite is expected to get even stronger over the next two weeks, so stock up now.
Hot spots today: Valued stretches include the Valley section below Emigrant—try from Mallard’s Rest down to Pine Creek—and above Yankee Jim if you’re looking for a bit more solitude and active fish. Paradise Valley still offers consistent action, though slightly more pressure. If you’re feeling adventurous, walk-wading the riffles near Springdale or Big Timber can deliver bonus fish with less company.
If you’re fishing inside Yellowstone Park, remember: some rivers like the Madison and Firehole are still closed due to low flows and warm water, so double-check the Park's current open waters and always handle fish quickly and gently as conditions remain stressful for native trout. Hit those early hours and bring a thermometer if you can.
Bear activity remains high in the region. Carry bear spray and stay alert, especially near campsites or when bushwhacking to new water.
