Current Conditions:
The Yellowstone River should start fishing well in the coming weeks. Most anglers will still be wade fishing and there will be significant ice to deal with for the foreseeable future. Nymph fishing will be the dominate source of action but dead drifting wooley buggers and small stonefly patterns, hares ears and big princes should start to produce as well. Make sure you are fishing the right kind of water that hold trout in the early spring. Once you find a good holding run you can get a lot of action in the after lunch hours.
The Month Ahead:
The Yellowstone should fish better and better as spring progresses, with hatches of march browns and spring baetis becoming more prevalent.
