Some of the Delta is tidal and other parts are mountain run off. Water warms up in the summer in sac river, but SF Bay is similar to chatham and North shore water temps.
My largest bass this year was only 32". A peanut by east coast standards. . . still fun on light outfits. The sloughs are neat to fish . . . there's 1,000 miles of little rivers and sloughs in the delta to explore. Really neat fishing spots, but the fish are smaller (at least the ones I catch).
