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 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 vector dataset includes features that represent water-table elevation (contour lines), groundwater flow direction (lines), a groundwater divide (polygon), and water wells within the study area (points). The data were compiled and interpreted for display at the 1:100,000-scale and may not be appropriate for use at other scales without verification.

Data Quality 

Lineage 

Lineage statement
Well construction report data for 660 wells, located within and adjacent to the study area, was derived from source files provided by the Wisconsin Department of Natural Resources in 2010. Records were reviewed for locational accuracy and other attributes of the wells captured on the WCR, such as well construction, hydrologic, and geologic observations. 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, in review). 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 agricultural regions were not similarly evaluated. In the data, those contours were assigned a confidence level of 'approximate' 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 to further illustrate primary groundwater flow. The features were digitized on-screen. 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 and to eps or pdf for use in final map production.

Data from the model provided initial water-table elevation contour lines which were then further refined for the two agricultural regions of the study area of this map.

Description
Well construction records (WCRs) were compiled from Wisconsin DNR sources (approximate dates 1988-2010). WCRs provided point locations and descriptions of geology, elevation and depth to bedrock.
