Delta bass and crappie settle into the fall transition

What's biting

What's next

Water temperatures in the mid-60s should keep drifting down slowly if nights stay cool, and that is the trigger for baitfish to push into creeks, sloughs and shallow cover. Expect largemouth to follow, so plan on covering shallow water with a moving bait early, then slowing down with a jig around wood and docks as the sun climbs.

Per Tactical Bassin, finesse presentations such as small swimbaits and tiny topwater baits can pull bites on tougher days, which is worth keeping in mind on bright, calm afternoons. Fishing the Midwest points out that green, living weeds often hold the fish in fall, because baitfish and gamefish relocate to whatever vegetation is still alive. In the Delta, that translates to hunting for the last healthy weed edges and tule margins.

The New Moon means dark nights, so the strongest feeding windows should be dawn and dusk rather than a midday push. Tidal influence in the Delta can shift current direction through the day, so check a local tide table and favor moving water over slack periods, since flow often triggers feeding around points and channel junctions.

Context

Mid-October is on schedule for the Delta's fall transition. Surface temperatures have come off the summer peak, and fish are moving out of deeper summer haunts toward shallower feeding areas as baitfish relocate. Crappie typically bunch up around cover and become easier to find, and bass key on forage rather than comfort. Anglers generally see better action on cool, overcast days than on stable, bright ones, so a front or cloud cover is worth chasing. Check current California regulations before harvesting.
