On any of the Park’s meadow streams, ie Lamar, Bechler, Madison, Fall, Lewis, Gibbon rivers, Boundary, Duck, Slough, Obsidian, Soda Butte creeks, its time to be the “Henry’s Fork Hunchback”. It’s a great time of the season to be on this type of water. But low, clear slow flowing water offers less overhead cover in mid summer, so fish are more skittish. Keep out of sight as much as possible and do everything you can to present those terrestrial patterns with a natural drift. Also best times for success are early and late in the day.
