The ramp you refer to behind the Shell opens up into a big bay with docks according to Google maps. If there is any water depth in there it sure looks like it would hold crappie. I fish similar areas up river in the Meldahl pool but most of our big bays or backwaters have silted in badly over the years. Just curious if the same problem exist downriver. I've never fished anything in the river West of Cincinnati, but hope to some day.
