Proven bait for me in Spring when fishing for Largemouth in high muddy water is to go to the backs of creeks and find the cleanest water possible in the bushes or grass and toss a black and blue chatterbait or spinnerbait.
Tossed buzzbaits up tight to the cover as well.
Has worked in the past and the last time it did we placed 1st, 2nd, 3rd and had big bass. Only boat to catch any 15" keepers that day.
