Mandle and Kontis (1992) and Young (1992a, b) provided the most comprehensive map of ground-water flow in the St. Peter-Prairie du Chien-Jordon aquifer in the region. Although their map does not explicitly cover south Illinois and western Kentucky, it clearly indicates that ground-water flow is downdip. Currently, ground-water flow in St. Peter Sandstone in the deepest portions of the basin is not well understood.<\/SPAN><\/SPAN><\/P>
