Merry Christmas and Happy Holidays from Rising Trout.

Recent warmer daytime highs and mild spells have kept stretches near Paradise Valley and Livingston fishable, especially when wind isn’t howling. Flows are low and clear this time of year, which gives wade anglers plenty of water to work but also means fish are spookier and holding tight in deeper runs and seams. Midday remains the best window to fish when water temps creep up just enough to coax trout into feeding.

As expected in early winter, nymphing is the go-to tactic on the Yellowstone. Trout are congregating in the deeper pools and slower water, and anglers are doing best with double-nymph rigs under an indicator fished near the bottom. Stonefly nymphs paired with small midges or slim attractors, and weight heavy enough to reach fish holding deep seams, have been productive. Streamer action hasn’t been as consistent but can draw follows on warmer, low-wind days when fish are a bit more motivated. Dry-fly opportunities are limited this time of year, although occasional midge activity can spark brief surface interest.

Looking ahead, winter conditions will continue to stay mild through the week with a cool down after Christmas. Look for possibly stronger winds, so careful planning around weather windows will pay off. Focus on deeper water near inside bends, buckets, and slower current edges where trout can conserve energy yet still feed. Midday fishing inside that warmest part of the day continues to outperform morning sessions, and being stealthy with light tippet and drag-free drifts will help in the low-clear water. Overall, the Yellowstone remains an option for winter fly fishing, especially for anglers willing to pick their days, adapt presentations to deep water, and be patient for subtle bites.
