Summary

These data accompany the "Generalized water-table elevation map in agricultural regions of Bayfield County, Wisconsin," plate 1 of Wisconsin Geological and Natural History Survey Technical Report 2. The map and a series of hydrogeologic cross sections (plate 2 of the report) were developed using information from over 660 wells located within and adjacent to the study area, previously published maps of surficial and bedrock geology, and an existing groundwater flow model. The compilation and interpretation of data was intended to support discussions and decisions surrounding land use in the study area.

Description

This polygon feature represents a major groundwater divide that is centered on the penninsula between the two agricultural regions in Bayfield County, Wisconsin. The water table slopes away from the divide: Groundwater to the northwest of the divide flows through the northwest agricultural region where it ultimately discharges to wells, tributary streams, and Lake Superior; to the southeast of the divide, most of the groundwater flows through the eastern agricultural region, discharging to wells, tributary streams, and Chequamegon Bay. Groundwater that originates south of the eastern region flows into the White River basin and Bibon Marsh.

Data Quality 

Lineage 

Lineage statement
Well construction report data for over 660 wells, located within and adjacent to the studyarea, was derived from source files provided by the Wisconsin Department of Natural Resources in 2010. Records were reviewed for locational accuracy and other attributes ofthe wells captured on the WCR, such as well construction, hydrologic, and geologicobservations. For the water-table elevation map and cross sections, wells were classified as being completed in one of three types of material: sediment (sand, or sand and gravel); sandstone; or bedrock other than sandstone, such as basalt. 

The map was developed from a model-simulated elevation of the water table (Bradbury and others, unpublished). The water-table elevation within the agricultural areas was subsequently refined by evaluating it for consistency with elevations of land surface, streams, lakes, and the reported groundwater level in wells completed above bedrock. Water-table contours outside the study areas were not similarly evaluated. In the data those contours were assigned a lower confidence level and on the map they are shown as dashed lines to indicate more uncertainty in their location. 

The groundwater divide and flow arrows were added by on-screen digitizing to further illustrate primary groundwater flow. Their position and direction should be considered conceptual.

Topology checks were made on feature geometry; and feature length and area measures were checked for appropriate values. Attribute values were validated to be within the appropriate domain. Visual inspections were made on-screen and using check plots. 

Geodatabase features were exported to shapefile format for digital distribution.
