Lineage: These files were made with water level information from two general sources: driller's logs from the County Well Index (CWI) database managed by the Minnesota Department of Health and the Minnesota Geological Survey with verified locations and measurements by DNR staff in conjunction with well sampling for this atlas project. The driller's log data were obtained from the CWI database and represent a data set that was collected over a period of several decades and spans seasonal and multi-year climatic trends of wet and dry conditions. Where the dataset included both CWI driller's log information and water levels collected by DNR staff, the DNR data were used. The potentiometric surfaces of the buried sand and gravel aquifers were created by interpolating hand drawn contours of static water-level elevations for wells constructed in each aquifer using the ArcGIS Topo to Raster tool. The Analysis Mask was set to the extent of the buried aquifer.
