Groundwater Levels in the Equus Beds Aquifer near Wichita, Kansas, January 2016

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.

本数据集为2016年1月对堪萨斯州威奇托附近埃克斯斯含水层（Equus Beds aquifer）地下水位的实测成果。本次针对该含水层的浅层与深层分区分别插值生成了测压水面（potentiometric surface），并将测压水面的栅格数据（raster）纳入本次公开数据集。本次依据测井站名将观测井划分为对应含水层浅层或深层的滤水管井（部分测井站名包含含水层分层标识）；若测井站名未提及含水层分层，则以井深作为划分依据：地面以下井深不足80英尺的为浅层观测井，80英尺及以上的为深层观测井。基于上述栅格数据生成了间隔为5英尺的等值线，用于绘制该含水层的地下水位分布图。本次地下水位实测数据可用于估算研究区在开发前（约1940年）、1993年历史低值期与2016年1月，以及2015年1月与2016年1月之间的储水量变化。
