If you’re planning on fishing the Clark Fork, here’s what you can expect, special thanks to Grizzly Hackle for the report:
The Clarkfork is really dirty, especially below where the Blackfoot dumps in. The Upper is fishable, but still a bit dirty. Remember you want at least 2 ft of visibility. Right now your best bet on the Upper Clark would be flashy streamers like Flash Minnows, Sparkle Minnows, Kreelex, Tandem Shiners and Bling Zonkers. Nymphing bigger rubberlegs and San Jauns is an option as well.
