Welcome aboard. First, muddy water usually warms faster than clear water so after the spawn they mostly move out to deeper water. They will relate to bottom contours over deep water. Not always on the bottom but over it. Do you fish from a boat? If so, try spider rigging over an the deep section. set your rods at different depths to find out how deep the fish are holding. Remember that there will be a thermocline so they may be shallower than you think. If you are fishing from the bank, set slip bobbers at different depths and fan cast out from the bank. hope this helps some. There are a lot of good people on this site that will more than help
