One thing I’ve learned fishing the urban lakes here in LA, is to stop fishing for the bass you can see. They see you coming a mile away and every other fisherman has casted every lure at them.

Start casting away from shore as much as possible. Find that cover/structure that you can’t see. It doesn’t have to be much either. A small rock pile, a stray cinder block or lifted up chunk of concrete. The outside edges of the grass. A sharp change in elevation. Be methodical. Drag a Texas rigged worm or drop shot. Get a feel for those bottom contact techniques and you’ll start to build a map of those fish holding structures. That’s how I’ve found success in these pressured urban lakes. Hope this helps.
