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 streamers. If you absolutely have to, try prospecting with Skwala and March Brown dries. Also, embrace the worm!


Prospect: Don’t be afraid to tie on a skwala or big march brown dry and prospect the runs, pools, and tail-outs.


Runoff is upon us. We expect flows to continue trending up, with limited topwater action until the Salmonflies come along.

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 on the upper to stained or moderately turbid at the mouth. Slippery rocks make wading difficult. Be sure to have studs in your boots.
