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 drillers log information and water levels collected by DNR staff, the DNR data were used. The potentiometric surface of the aquifers were created by labeling the water elevation values next to the well locations in Arc GIS with both a topographic DEM and a topographic map as background layers. Water elevation contours were drawn as 20-foot contours by digitizing on-screen using the land topography background layers as a guide in areas where data were scarce.
