The Upper Scioto always tends to be muddy. The first time I scouted the Upper Scioto, I asked myself, "Why is it so muddy?" It was the middle of summer without much rain, and it was ugly muddy. This year it is muddier than usual because there is more rain than usual. It would be less muddy overall if good farming and drainage practices were followed.
The river fish are not biting as well there for the same reason that they aren't biting anywhere...they aren't biting.
If your creek is muddy, they aren't biting is because it is muddy. If your creek isn't muddy, they aren't biting because of something else. All I know is that the fish aren't biting. Maybe they will bite tomorrow, but maybe they won't because the water is muddy. If it isn't muddy, I don't know why they aren't biting. Maybe the water is too clear. Maybe it is too muddy.
