Awesome that the whole family went. Mine did a few times, but most of them don't want to go. Or at least they've outgrown going with us. LOL Those are some nice bream!
Have you spent any time fishing at the water treatment discharge pipe? The big one on the left just below Elephant Rock? I always catch some bass there. Often there are some nice schools of good sized ones hanging around in that white water current. Cast a squarebill, spinnerbait, rattletrap, etc. right up under the pipe and get the aggressive ones. Then you can usually switch to a rubber worm and pick off some more.
