YELLOWSTONE RIVER FISHING REPORT

by Artificial Lure, Angling Expert

Good morning, folks! Artificial Lure here with your Sunday fishing report for the Yellowstone River. It's shaping up to be a fantastic day on the water with the spring fishing season in full swing.

Weather's looking mighty fine today with temperatures expected to climb into the mid-60s by afternoon. Sunrise was at 5:42 AM, and we're looking at sunset around 8:52 PM, giving you plenty of daylight hours to land that trophy catch. There's a light breeze from the west, perfect for keeping the bugs at bay without messing with your casting.

The Yellowstone is running clearer than last week, though still carrying some spring turbidity. Water levels are moderate following the recent rainfall, creating prime conditions for our native species. No tidal report needed here, of course - we're mountain folk with freestone rivers!

The big news is that Yellowstone cutthroat trout are hitting hard right now. These beautiful natives are the dominant fish species in these waters and they're feeding aggressively in the morning hours. Anglers working the riffles and pools between Gardiner and Emigrant have reported solid catches of 14-18 inch cutties, with a few trophy 20+ inchers in the mix.

Our other native game fish, the Arctic grayling, have also been active, particularly in the cooler tributary waters. A few lucky anglers connected with these prehistoric beauties in the upper sections near the park boundary. Remember, grayling are catch-and-release only, folks.

Mountain whitefish numbers remain strong, providing reliable action when the trout get finicky. These natives might not be as glamorous as their salmonid cousins, but they'll bend your rod just fine.

For those targeting non-natives, rainbow and brown trout have been hitting consistently, especially in the afternoon hours as water temperatures rise slightly.

Lure-wise, small spoons in copper or silver have been producing consistently. Mepps spinners in sizes 1 and 2 with gold blades are turning heads, particularly for the cutthroat. If you're a fly fisher, caddis patterns and small stonefly imitations are your best bet right now, with size 14-16 Adams patterns working during afternoon hatches.

For bait anglers, small nightcrawler pieces or salmon eggs under a light float have been effective, especially for the whitefish and non-native species.

Hot spots this week include the stretch below Yankee Jim Canyon for bigger browns, the pools near Mallard's Rest for consistent cutthroat action, and the confluence areas of major tributaries like the Gardner River for mixed-bag fishing.

Remember, the 2025 annual fishing permits are now valid for the calendar year, so make sure yours is current before heading out.

Tight lines and wet waders, friends!
