Yellowstone River: The stone is fishing well! Its running at 2740CFS and has been fishing great for the most part. The upper reaches of the river are the places to be if you are looking to throw bigger dry flies and get surface eats. The fish have been keyed in on smaller PMD imitations and caddis fished behind larger chubby chernobyls or water walkers. As you move down river, the bite changes. The valley is seeing better trico and hopper fishing each day but a dry dropper rig is still the best option for consistent action. Things are starting to warm up from the valley down so try to get out early on in the morning. Fishing has been cyclical below about mallards rest. You will have a good hour of fishing and then a bad couple hours, then another good hour or two and then it will shut off again. Stick out these slow portions and your patience will be rewarded! Watch for storms moving through the valley and further south. Swinging small sculpin imitations has also been picking up fish, especially with the cooler weather and artificial cloud cover(smoke).
