I believe you I was at Stillhouse and saw the weirdest thing, the crappie were in 15 fow but suspended 2-3 foot below the surface caught 8 really quick and then the shut off like a light switch they just stood there open and shutting their mouths I would guess they were eating some really small stuff but wouldn't hit a minnow, worm jig nothing!
All caught on jigs from the bank. 4 fow and less.
