Our Report

Rock Creek is perhaps the best option in the Clark Fork drainage for consistent winter and early spring angling.  During this time of year, trout are more and more concentrated in the deeper runs and out of the long shallows they inhabit throughout the summer and fall. Nymphing and swinging are the name of the game, but do not rule out rising fish during midge hatches on warmer days, especially when the sun is on the water.

BEST TECHNIQUES – Nymphing and swinging streamers.


Visibility: Water visibility may begin to fluctuate with (hopefully) warmer days and some snow melt. Remember to size down on fly AND tippet with low and gin clear water. With a bump in flows and normal to stained water, size up on fly and tippet.

7 DAY OUTLOOK – With temperatures at least sort of above freezing during most of the day in the next week, look for the potential to fish all day. Skwalas and March Browns should be out any day, if they’re not already. Tight lines!

Good luck from the team at Blackfoot River Outfitters and Flint Creek Outdoors! FCO in Pburg is open this spring Wed-Sun. Be sure to stop in to meet Josh and for your Orvis gear and the best fly selection in the region.


Low and clear but super slick for wading so take your wading staff, cleats and care.
