Figure 1. Extent of the Dakota aquifer in Kansas showing regions of hydraulic connection to other aquifers, where the Dakota is a near surface aquifer, and where it is confined by relatively impervious units.
The proportion of sandstone to the total thickness of the stratigraphic units that constitute the Dakota aquifer is approximately 30% statewide. However, locally this proportion can vary widely from less than 5% to more than 50% over short distances. The sandstone aquifers contained in these Cretaceous units occur as irregular, discontinuous bodies within the mudstone and generally occur in several, more or less distinct zones.
