Slough Creek is fishing very well after a somewhat late start. Brown and gray drakes are pretty much done for the year. Same can be said for Fall River Basin streams. On both the above waters ant and beetle patterns are almost sure-fire when fished around cover abnd overhangs. Beula and Riddle lakes still offer great fishing for those using damselfly and speckled dun life cycle patterns. Forget the Firehole until September but look for hoppers and other terrestrials to work on the Madison, Gibbon and Gallatin rivers, and Duck, Cougar and Grayling creeks.
