Our Report


Rock Creek is looking great for the fall.


1. You’ll find fish spread all over the river. Don’t overlook the fast shallow water.
2. They’re looking up. Try a hopper or ant.
3. Look out for moose.

BEST TECHNIQUES – Dries, dries with a short-depth dropper, nymphing.

Good luck and don’t forget to stop in our Philipsburg shop Flint Creek Outdoors and our NEW JACKALOPE JOE’S espresso bar! We’re open 7:30-5 seven days a week. Be sure to stop in to talk to Josh, grab a coffee, some Orvis gear, and flies from the the best fly selection in the region.
