Yellowstone National Park, September 11th, 2021

Nearly all park streams offer sub par fishing because of the unusual hot and dry weather continuing for months. It is cooling off, so lakes at higher elevations, such as Beula, Hering and Riddle offer some fishing. The annual brown and rainbow migration out of Hebgen Lake into the Madison River has begun, and crowds will build along the river as the run progresses. The same will happen along the Lewis River below Lewis Lake and between that lake and Shoshone Lake where the densest brown trout migration in the park occurs. The Firehole River is cooling and thus offering better conditions for trout meaning a visit to fly fish is worthy..
