Recent reports on the delta are mixed depending on when and where you are fishing. Some anglers are having good success with poppers one day, spooks the next and once the wind picks up, the Bass are eating spinner baits and chatter baits. Fish are being caught on a variety of reaction baits 25 to 30 feet from shore, while others are fishing shallow and targeting grass.
Other anglers are taking a completely different approach and primarily focusing on post-spawn females that are hiding out and recovering from the spawn under the dense mat cover. The fish that have already spawned are moving back to the mats to feed on bluegill. That really doesn’t happen anywhere else but on the Delta. If you can find those good areas, you can catch them pretty good!
In almost any of the above scenarios, the real keys for success will be a combination of tides and water temperature.
