Our Report

Rock Creek Road is now open from the bottom and continues to produce in spite of the heat wave we endured this summer in Western Montana.  Water temps are starting to drop in light of heavy smoke, followed by a bit of rain and clouds together with shorter days and longer nights.The fishing on Rock Creek should get nothing but better for the foreseeable future.

BEST TECHNIQUES – Look for trico spinner fall (and maybe a few spruce moths) on the water mid morning and hit ’em hard as the hatch will dwindle a little after noon. Later in the day try long droppers or short leash nymph rigs in the deep channels for brownies.

TIPS OF THE WEEK – When fishing tricos the fish can be picky – first try to match the size … once they see your offering a few times and don’t commit don’t give up – try a different style (spinner, thorax…)

7 DAY OUTLOOK – Cooler temps predicted starting Monday……and rain! The smoke from the fires is acting like a nice cloud cover so the fishing is pretty good here right now.

Rock Creek road is open now from the confluence to Harry’s Flat campground. The top portion of the road is still closed due to fire in the area.

Good luck from the team at Blackfoot River Outfitters and Flint Creek Outdoors! FCO in Pburg is back on for the season – open every day. 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.
