Alder Lake Saturday

I'll be camping at Alder Lake Park this Saturday.  So likely trolling for some Kokes Saturday afternoon/evening and Sunday morning.  I usually catch quite a few out there, we'll see how I do when the waters still on the cold side of things.

How big do they run? How deep do you have to fish? Any certain part of the lake?

North end of the lake is best.  During the summer I catch them 20-30 feet down.  Not sure where they'll be now.  They are usually 12-14 inches.
