I think your best bet for closest lake and quality bass is silverwood but the bite is tough up there and pretty much every where right now!I really could not tell you a good pattern right now at silverwood,maybe someone else could(sorry)As far as corona lakes i've been there and have seen pic's of bass,unfortunately most people there are trout and catfish fisherman(meat eaters)and most bass caught don't make it back into the water!All I can tell you from seeing the place is that it's usually stained to muddy water and one side of the lake is half submerged trees.That's probably a good spot,only excessable by boat and lot's of cover.I'd bring some hefty line though,break off city right there!!!

Good luck....tight lines....release those phatties....
and damn my spelling sucks....stay in skool.....
