The Yellowstone has been fishing well despite its lower flows sitting in at 1600cfs. With the recent weather you may see a bit of color but it should push through fairly quick. It's that time of year were the Stone is wade friendly, however beware of slick rocks. Cooler nights have kept the water cold and hoppers are everywhere, however the fish aren't always keying in on the tasty treats. The best way to test the waters is Hopper or Micro Chubby droppers with Baetis, green caddis, perdigons, blow torch or any cdc soft hackle nymph variant. Streamer fishing has been decent and will pick up more with the cooler temps. Check the wind before heading out, it has been picking up in the afternoons a bit.
