Don't give up on those cliffs. A lot of them have old cedar trees growing out of them down about 20-35'. If you fine the brush, fish it. Jigs , A-rigs, deep divers. I fish a hair jig and let it fall slowly on loose line. You can stick some good fish that way. In the afternoon, after the sun has worked its magic on the rocks, go fish the shoal side of the lake 2' to about 5'. you can find them sunning themselves on the rocks. I use a jerk bait fished slow, but any of your favorites will work presented right.
To me, PK is a winter lake. One of the best spots to fish when its cold is Scenic Point, give it a try
