The blackfoot starts fishing in late june/ golden stones, maybee some salmon flies. I usually guide a few days on the Foot then, in Late june if the runoff isn't too bad. Close to Missoula in July/ August you will see lots on tubers so I would fish at least 30 miles upstream from Missoula, stimulators, cuttthroat stuff. Rock Creek will be real good it is real hard to wade fish it in June, too high, but you can wade fish the whole creek July- october. We guide it and run float trips in June on rock Creek, but you want to be experienced on the oars if you do it yourself. check us out if you want more fishing/ lodging info around Missoula Montana Fly Fishing, Missoula Montana, Montana Fly Fishing for Trout.
