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 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.

Static water elevation data from CWI and DNR project data as described above for each particular aquifer were posted on individual maps with elevation data from major rivers as a reference. These data were contoured with the Topo to Raster tool (no drainage enforcement) to produce an elevation raster per aquifer unit. The analysis mask was set to the extent of the buried aquifer.

Field NameValid ValuesDefinitionDefinition Source
AQUIFER_Q
-
Quaternary aquifer name, usually mapped at county scale. Quaternary aquifers are named after buried sand units shown on Plate 5, Part A. Bedrock aquifers are represented by "bdrk".
AQUIFER
-
County Well Index aquifer code.
CONTOUR
-
Modeled potentiometric surface contours of the buried sand and gravel and bedrock aquifers.
LN_TYPEenumeratedPotentiometric contours are attributed as dashed or solid lines to communicate uncertainty and association with mapped sand aquifers.
SolidPortion of contour that overlies mapped aquifer polygons
DashedPortion of contour between mapped aquifer polygons, displayed for visual continuity and to help the map user understand the overall flow patterns
