Good morning anglers, this is Artificial Lure with your Yellowstone River fishing report for Saturday, May 3, 2025.
We woke up to a cool spring morning along the Yellowstone River, with temps starting in the mid-40s and expected to climb into the high 60s by afternoon. Skies are mostly clear early, but afternoon clouds and a light wind out of the west are forecast. Sunrise was at 6:05 AM and sunset will be at 8:32 PM, giving plenty of daylight for a full day on the water. Remember, the Yellowstone River is not subject to tides, so water levels are primarily influenced by recent rains and snowmelt. Flows are running a bit high but clear enough for good fishing after a relatively dry week.
Trout activity is picking up with the warming trend. Anglers this week have done well on cutthroat trout, rainbow trout, and mountain whitefish, with a few reports of healthy brown trout being landed as well. The best bite has been during mid-morning and late afternoon, as the water warms and insect hatches pick up. Caddis and blue-winged olive hatches are coming off strong, especially near riffles and gravel bars.
For gear, dry flies like elk hair caddis and parachute Adams in sizes 14 to 18 are working well on top, particularly in the slower side channels and back eddies. Nymphing with beadhead pheasant tails, hare’s ears, and stonefly patterns has produced consistent action, especially in deeper runs. If you are tossing lures, small spinners in gold or silver and natural-colored crankbaits have raised some aggressive fish.
Live bait is not permitted in most sections of the Yellowstone in and around the park, so stick to artificial flies and lures. For those fishing outside of the park boundaries, worms can get results for whitefish and the occasional large trout, but artificial baits are the way to go for quality fish and compliance.
Hot spots to check out today are the section around Livingston, where side channels provide varied habitat for both trout and whitefish, and the stretch near Emigrant, known for its access and healthy numbers of cutthroat and rainbow trout. Reports from anglers drifting downstream of Gardiner say the bite is solid on the inside bends and near rocky structure.
Overall, fishing is only going to get better as the spring progresses and water temps warm up. Remember to check local regulations and respect the delicate balance of native fish in the river. Tight lines, and enjoy your day on the fabled Yellowstone!
This is Artificial Lure, wishing you good luck and smooth drifts!
