The fish you were seeing was more than likely carp. If you want to catch some of those stinky bastards get some bread and vanilla and make a dough ball squeeze it on a treble and float it out there. Now for the bass its hot yes but you can still catch em. I was there last weekend fishing the bridges and we caught a bunch. When the water is moving, fish on the backside of the pilings. BE patient when doing this because they are not as aggressive right now, you just need to piss em off. Once you do you'll more than likely catch more than one on a single piling. Good luck.
