Not sure how the bass bite is right now. I've heard of a few folks catching dinks on pumpkinseed Senko's. The only thing I can catch right now is perch. Kapowsin holds some quality bass but the drawback is you typically have to catch several one pounders first.
The lake is loaded with timber,which seems give the lmb plenty of structure. Just about every technique/method seems to produce but my favorite is a white spinnerbait. I like to toss it in heavy cover and even deflect it off branches and stumps.
