Yellowstone River Fishing: Browns and Rainbows Rising as Runoff Drops

Artificial Lure here with your Yellowstone River fishing report out of south‑central Montana, talking the stretch from Gardiner down through Livingston and into the valley. First off, no tides to worry about on this inland river, just flows and weather. Overnight we’ve had cool temps in the low 40s with clear skies. Afternoon highs are pushing into the upper 70s to low 80s with low humidity, light west winds 5–10 mph, and only a slight chance of a pop‑up shower over the higher ground. Sunrise is right around 5:30 a.m., sunset close to 9:15 p.m., giving us a long daylight window. River levels are dropping out of peak runoff and finally getting into shape. The upper river above Livingston is still carrying some color, but visibility has improved enough that fish are feeding off the banks and in the softer seams. Below Livingston, the water’s a touch clearer with that good green tint we like to see this time of year. Fish activity has picked up nicely the last few days. Anglers have been reporting steady numbers of **brown trout** in the 14–18 inch range, a mix of **rainbows** from 12–16, and the occasional larger fish nudging 20 inches. A few **whitefish** are still showing up in deeper runs, especially where the current slows and the bottom is cobbly. Boats working the mid‑day window are finding fewer but larger fish, while wade anglers getting out at first light are seeing the best numbers. On the bug front, we’re in that shoulder period between heavy runoff and true summer hatches. Expect scattered **caddis** in the evenings and a few straggler **PMDs** and **yellow sallies** midday. Terrestrial action is just starting—small **ants** and **hoppers** will get looks, especially on the banks with good grass and overhanging brush. Best bets for fly anglers: - **Nymphs:** Size 12–14 beadhead Pheasant Tails, Prince Nymphs, and smaller stonefly nymphs in size 8–10 under an indicator. Add a bit of weight to punch through the chop. - **Dries:** Elk Hair Caddis in olive or tan size 14–16 toward evening, parachute Adams size 14 for picky risers, and small black ants when the sun’s high. - **Streamers:** Olive or black articulated patterns and smaller sculpin imitations on a sink tip early and late; swing them off the bank and through inside corners. Gear anglers are doing well with: - **Lures:** 1/8–1/4 oz **spinners** in gold or copper, small **crankbaits** in brown trout or rainbow patterns, and **spoons** in the deeper slots. - **Bait:** Where legal and appropriate, nightcrawlers drifted under a small float or on a light bottom rig are taking both trout and whitefish. Check local regulations carefully—some sections are artificial‑only and barbless. A couple of local hot spots to keep in mind: - The **Pine Creek to Carter’s Bridge** stretch below Livingston: good mix of riffles, buckets, and soft banks, with browns holding tight to structure as the water drops. - The **Yankee Jim Canyon tailout** down toward Gardiner: tricky rowing but excellent holding water when clarity is right—this is where those better‑than‑average browns have been coming from on streamers. Fishing is best from **first light to about 11 a.m.**, then again after **7 p.m.** when the sun drops behind the hills and the caddis start popping. Midday can still produce if you go deep with nymphs or slow‑roll streamers along the bottom, but expect to work a bit harder for each grab. That’s the Yellowstone River rundown from Artificial Lure.
