I was on the Niangua over Mom's day weekend and we never fished deeper than 4 ft. Averaged about 30 over 10 inches each day but some areas were choked full of little ones as well. Lots of females still bulging with eggs. It was still really muddy but I think that just pushed the fish even shallower. We caught several in honestly 6 inches of water. Sunday the bite seemed to slow a little but that may have been due to the bright sun and glassy water. I would guess you can find some still shallow next weekend but I imagine a good bulk of them will be moving back out. I talked to guy that was catching good fish on the creek channels already.
