Get all your buddies lined up and chuck jigs and pull every one you can get caught-out... at this point that's all you can do. It's all hands on deck, you can make a difference if you put in the time.
Another crappie catch technique is set Z traps or cloverleaf traps with glow sticks in the center (at night) and float the traps with noodles as close to the surface as you can.
