Go to the general store and get a map of the lakes in the park. The map will also tell you what kind of fish are in each lake. There is some good trout fishing up there.......I don't bother with the bass.......too easy.
Just troll a worm harness with a half worm around the middle of the lake. Let out a full cast, then two rips of line, and just troll along slow. You should get a trout, I always do. They should be 10-15ft down, over the main basin somewhere. Don't forget, they feed a lot off the surface, so don't try too hard to get down deep, you'll be fishing under them, and won't get bit. Your better off to be over them. They'll come up a long ways to check out your offerings.........getting them to bite it is another story. It should still be decent though.
