Look for fish responding to BWO, mahogany duns, morning tricos, afternoon caddis, ants, beetles and hoppers anywhere you try the river from Last Chance to below St. Anthony. Crowds are gone just about everywhere, but especially from the Last Chance-Harriman section. A killing frost could happen any day, especially on the upper river and wipe out hoppers and slow ants and beetles. But BWOs and caddis will remain active for quite a while. Streamer fishing will pick up on the lower river as browns begin to migrate.
