Well after two consecutive days of fishing on the Delta I still have no clue. Friday the 21st was a bit chilly and breezy with predicted highs around 78 degrees. It took a while but about 1pm it really warmed up. The bite was on, fish were moving shallow and eating. I caught them punching, frogs, flipping beaver style baits and chatter baits. The chatter fish were on rock walls with wind blowing into them. When they hit it there was no doubt. The frog fish were very aggressive and quick. Throwing the frog in the troughs produced quick bites for fish from 2 to 4 lbs. The punch fish were a little more fickle but the quality was much better with fish to 8 lbs for me on Friday. Flipping beaver baits into tule pockets in protected areas is an old standby and also produced fish to 8 lbs for me on Friday. I fished south to middle Delta and just bounced around trying to find some areas with numbers of fish. Water temps started out at 60 deg and got up to 67 in some protected areas by afternoon .
