(Currently under hoot owl restrictions from highway 89 bridge to laurel) https://fwp.mt.gov/news/current-closures-restrictions/waterbody-closures. The Yellowstone flows are currently at 3600 at livingston. The fishing has been better in the mornings with all this hot weather we have experienced recently. The river is getting up to about 72 degrees in the afternoon. Nymphing has been killer with rubberlegs/girdle bugs, zirdles, FKA princes, cdc pheasant tails, hare's ears, duracell's, blowtorch's, and jig streamers like GDP jigs, tungsten striptease, and backflop jigs. Lots of whitefish on nymphs. If you are targeting trout try dries or a really short tag dry dropper. Dry flies are turning back on with caddis, purple hazes, parachute adams, chubbies, hippie stompers, and ant's all crushing fish. Up higher on the river has been better overall since it is slightly colder up there. Streamers like the dungeon, dragons, peanut envy's, rusty trombones, goldies, chromatic peanut, kill whitey's, and sluggo's have all been ones to try if you want to try and get on some fish chasing big flies.
