Fished Big Twin Lake for the opener this year and did pretty well. We got there on Saturday and had caught our limits within minutes, though they were relatively small. Saw some float tube anglers pull in some nice size cutthroat though. We fished there again the next morning and didn't do as well, the fishing had slowed considerably. My uncle did manage to pull out a nice 24" cutthroat on a black woolley bugger. The next morning was even slower yet, but some of the fish were bigger, around 16 inches. The lake as of yet hadn't been stocked this spring because of a late winter, so hopefully when it is, the fishing will be terrific.
