Up above that bridge a short ways is what is called falling water rocks. It is on your left bank going up. Between there and the bridge, at one time, was some hot area for rockfish. Top baits were the biggest topwater rapala and a fluke. When fishing the big redfin, had the same experience as you. If you can find an old, large Johnson Silver spoon, that might work. Saw a man catch six in a row with one. He had a big piece of white pork rind trailer and cast upstream about six feet out from the rocks. As it came by the rocks, he would slow way down and let it flutter like a dying shad.
WHAM! On six straight casts.
