So I have been trying to catch some fish in the River anywhere from Louisville to Mayesville. I have done pretty well near Louisville especially in May-July. Later in the year (Aug-Sept) I always struggle.

This year I have been finding more deep (8-18 ft) structure and cover that looks pretty good on my SI.(Small ledges, Deep stumps, Log jams, etc) I have tried to fish it, but don't do well on it either. I think that it may be too deep for the fish where the silt chokes or out oxygen or I am just not fishing it well enough due to my concerns about holding fish.

So I ask you all, do you do any good fishing deep on the Ohio or similar rivers? How deep do you consider too deep?
