This dataset is the result of measurements of groundwater levels in the Equus Beds aquifer near Wichita, Kansas, in January 2016. Potentiometric surfaces are interpolated for the shallow and deep parts of the aquifer, and rasters of the potentiometric surfaces are included in this data release. Wells were classified as being screened in the shallow or deep parts of the aquifer based on station name (some wells have a layer identifier in the station name) or, if no indication of aquifer layer was given in the station name, based on the depth of the well; wells with depths less than 80 feet below land surface were classified as shallow and wells with depths of 80 feet or deeper were classified as deep. Contours with a 5 foot interval were produced from the rasters and used to map the water levels in the aquifer. The water level measurements can be used to estimate storage-volume change in the study area between predevelopment (circa 1940) and January 2016 the historic low in 1993 and January 2016; and January 2015 and January 2016.
