Its been a while since I've fished it, but trolling for trout is easy with good action most of the time. A wedding ring with corn or a worm trolled a long ways behind the boat caught many fish. its shallower towards town and it seemed the trout were at that end back then.

Kokanee hit several different things, even herring while I was after the land locked Kings, just deeper than trout and further towards Wapato point.

Lakers are on the bottom, I never did catch any back then, so I can't say what worked.

Bass were already covered.

Do search here on "Lake Chelan" and you should find a great deal of info.
