Spruce moth patterns are producing on the lower end of the Madison in the Park and on the upper reached of the Gallatin in the Park. Terrestrials are bringing action on all streams, and caddis swarms provide evening action. The Snake River at the South Entrance can offer great action this time of year for those offering terrestrial patterns. This is also a great place to offer humpys; they make a great horsefly imitation. The best still water action in the Park is on Beula Lake. Action on Riddle lake is bad either.
