Flowing at 370 CFS at Gallatin Gateway, the Gallatin continues to be a solid fall fishing spot, according to The Rivers Edge on November 20, 2025. The warmer weather is keeping some dry fly action alive, but you really can’t go wrong with a trusty double nymph rig. Throw a stonefly imitation followed by a smaller nymph into deep pockets or slower runs, and you are in for some consistent takes. Top flies right now are Pat’s Rubberlegs Black #10, Jig Frenchie #14, Parachute Adams #20, Zebra Midge Black #16, and the ever-reliable Autumn Splendor #6.
