Star Lake in West Auburn (WA) has lots of Rock Bass. I've fished most the lakes on the ridge there, targeting LM. Star Lake, I was on just the one time, and caught at least a dozen Rock Bass before I got a LM...and promptly loaded up my canoe and left. I think I was using 4" black/chart Ringworms. I pretty much quit using chartreuse tails, just because they caught too many perch, bluegills, and rock bass. Generally, I consider my season a success if I don't catch any perch or trout.
