Yellowstone National Park, September 25th, 2021

Crowds are beginning to arrive to fish the brown and rainbow trout migration out of Hebgen Lake and into the Madison River in the Park and into the Lewis River above and below Lewis Lake. The earliest possible arrival in the day at both places will result in the most tranquil fishing. Unsettled weather, such as predicted for the middle of the upcoming week, means more active fish and fewer fly fishers visiting. The best strategy for encountering these fish is to swing large streamer patterns deep through runs and holes using a sink tip line.
