Our Report

BEST TECHNIQUES – Nymphing, headhunting for midge and skwala sippers.


1. Cast your nymph into the faster water just above the dumps to get it down quicker.
2. Nymph deeper pools where the fish aren’t rising.
3. There may be fish rising to midges or skwalas. Keep an eye out!

7 DAY OUTLOOK – Winter flows are good. Some shelf ice around. Midges, Skwalas, and March Browns should be active in the coming weeks.

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.
