Heading out to Eastern Idaho on June 23 for some days. Probably will be in the panhandle forest for eight days. Heading back to W. Montana (other than a week or so in YS and Madison Valley) for the rest of the summer until August 15th. I don't expect anyone to spot burn, but any rec's aside from the big ones in the panhandle of Idaho? We'll probably spend a few days in the CDA and St. Joe drainages, so looking for any spectacular tribs in those areas. Same goes for W. Montana - have fished RC, BF, etc extensively, so smaller stuff that is preferably within two hours of Missoula as that is our home base. Feel free to PM.
i live in CdA, and travel through Montana all the time. Fishing on the CDA (Kingston Exit, Interstate 90) and then going upstream until you can safely wade is excellent right now. Probably mile marker 20 to 40 if I were to go out today. I have fished up to mile marker 5 since early May because it‘s convenient. Fishing 0 MM to MM 20 is still possible, but the water is deceptively fast and you won‘t be able to reach all the holes without crisscrossing. Sometimes i take my inflatable just so I can cross. Dry flies: Adams, Parachute Adams, smaller mayflies, griffith’s gnat, caddis, prince nymphs, madam x, yellow humpy, purple haze.
Half way between CDA and Missoula is a gorgeous stream called St Regis River. I fished there 2x already this year. Still a little high, but shaping up everyday, even wet wadded last week. It was 87 degrees. Same flies. Stay lower. This river dumps into the Clark Fork River. The Clark Fork is chocolate brown right now. From that point up stream at most 3 miles, are the best waters. Go any higher and the fish are small.
The St Joe isn’t fishable until July. The run off is later and hard to time. If you go too late, the water gets skinny and the upper stretches just don’t fish well. I don‘t fish the lower St Joe because there are tons of people rafting and partying on tied together tubes. If you go, go all the way to the top. There is a camp site call Spruce, and then walk up the horse trail for about 2 miles and then fish back to camp. Mid to late July would be the earliest I would personally go there.
Blackfoot River just a few miles west of Lincoln, MT is a favorite of mine. August, Sept and Oct are best. South of Missoula is the Bitterroot. It too drains into the Clark Fork. I drove past it last week. Still high and 75% clear. it probably needs 3 weeks before it‘s wade fishing again.
