Musky said it. Browns seems to turn off right around New Years, thats when I quit fishing it. If you really want rainbows, I would suggest going to Georgetown, even though it's a drive from Seeley. Or Canyon Ferry. Nevada Reservoir has some cutthroat, as does Placid Lake. Gotta work for them though. Perch and Pike in the Clearwater chain of lakes. Lakers in Swan lake. If you have sleds, you could probably get to some lakes in the Missions that have trout, but I don't know for sure. Might be worth a call to Lolo National Forest Seeley Ranger Station or a search on the Montana FWP website. Pretty good info on species under the Fishing Guide tab. Good luck.
