Our Report

Winter is a-coming but it is not quite here yet. Won’t be long. We are still having some success on the lower Clark below town. The window is getting shorter for the dry flies, but the deep dropper is still getting it done.

BEST TECHNIQUES – Double nymph rigs with something tungsten to keep it tight to the indicator so that you don’t miss strikes.

OUR TIPS OF THE WEEK – Look for tricos emerging in the evening and the spinner fall in the morning. Caddis, hoppers, and other terrestrials have been working, along with dry-droppers during the day.

7 DAY OUTLOOK – See above for the weather forecast. We are still above freezing, so you can get out and make it happen and the cloud cover never hurts.

Call or email us for up to the minute updates at 406.542.7411 or if you are in the area stop in our fly shop and say hi at 3055 North Reserve Street in Missoula for all your Orvis gear and the right bugs.
