Lake Chabot is a wonderful hidden gem. I've pulled a few over 8 out of there. San Pablo is primarily a spotted bass fishery... it can be tough, but there's some big girls in there and I've heard of a few largemouth over 10 over the last couple of years as well. If you have the means to get off the bank (yak is my preferred method!), the Delta is a bass fisherman's dream. Same can be said for Berryessa in Napa. Berry is grossly underrated and I personally think it's a better fishery than Clear Lake.
