Fishing Report Updated September 5, 2021
Small mountain creeks draining into the Yellowstone, Gallatin, and other rivers are still a good bet in the afternoons. They will remain good until the first major cold spell, usually around September 20. Fish hopper/dropper rigs in deeper areas that you don’t think have been fished lately. Make sure to fish upstream of irrigation diversions, which typically occur where the creek’s own valley hits the valley of the larger river into which the creek feeds. Even though many irrigation pumps are being turned off now, the areas downstream of diversions would have been completely or almost dry from mid-late July until just recently.
Meadow-type creeks are NOT a good choice now due to irrigation drawdowns. Unless we’re talking about the hike-in meadows on the upper West Boulder, stick to the fast mountain streams.
