I would run deeper water or just adjacent to the deeper water paying attention to an kind of additional attractant like structure and I would look for the shad schools and use something that imitated them. I doubt there is a day that someone does not catch fish vertical on a brush pile it's a Rend speciality.And I would say part of the day that will be right. But I fished Gunn creek one day last fall and caught a lot of fish chasing shad by casting ...but it was a rainy day with a front pushing through.Sunny and warm ...bet they hold on cover a good part of the day..but should get active at least part of the day. In September I almost always catch fish good the last hour or two of the day chasing shad or shad fry.
