muddy water tourunament

ok i have a tournament tomorrow and its been raining all night really hard and this lake is 2000 acres and there is a river that flows in it and we caught only one keeper in practice and caught 3 shorts. lost two other keeper ones the one we caught that was a keeper was by a dock on a skitterpop and the other two we were skipping and we lost them. the docks are different then most lakes around here they go from one foot to like 8 foot really quick so idk where the fish are holding on them. but thats what all the locals say to do to catch the bass there. but if the water is muddy idk how were going to catch them if we couldnt cath them in stained water. also there is a  big bay the water is way colder then the rest of the lake that is about 80 degrees and the bay is about 65 we saw one bass in there about 17 inches. so would that be a good spot to try? some help would be great. thanks guys
