Fall run browns are beginning to show up in the Madison River above Hebgen Lake. Rainbows will follow soon. Fall green drakes (hecuba) are showing up in Soda Butte and Slough Creeks and the Lamar River making for another component for great dry fly fishing. Terrestrial patterns along with Epeorus life cycle patterns are also in the mix. Fall River Basin streams feature morning trico activity with terrestrial patterns taking over for action around mid day. Thunder showery weather will result in best action on all these streams.
