Glad you had a great trip!
I lived in Cascade for 6 years and fished the river anytime there wasn't ice on it. October always treated me well. If you know what you are doing on that river, you can often catch 12 or more trout an hour. It definitely ruins you for normal trout fishing though.
Wind! What wind!? You'll know when it is really blowing when you see a semi-truck get blown over on its side on I-15 as you are traveling south from Great Falls where I was working to Cascade where I lived. If the wind is blowing like it was the day I saw the semi-get blown over, it is too much wind to fish. Otherwise, a nice 15-30 mph breeze just keeps the duffers away.
Side note, did you happen to stop in the Mountain Palace? It has decent food, great atmosphere, good beer, and good company. And on Friday and Saturday nights they used to have live music. And who needs cell service in such a beautiful place on such a great river?
Yes, you know the area well.
This river will definitely spoil you - never have I caught so many fish on every single day ever!
Now I don't have any inclination to go trout fishing anywhere else now...
Matter of fact, I am already planning a Mo trip for next fall with my local fly club and I get to lead it because I am so stoked about this river.
I did notice the Mountain Palace inn at the boat launch but did not get to stop in - looked dark like it was closed for the season ?
A lot of places had closed for the season - Izaaks in Craig and Oasis in Wolf Creek had closed.
As a matter of fact, we were able to get half off prices at Izaaks on the last day of the open night....
The wind is ferocious - yes it is but 15-30MPH is too much for most anglers. The group I went with ended up with chapped wind burnt face and lips!
Had to run over to the fly shop and buy a lot of Simms lip balm!
