Title:
Generalized water-table elevation map for Bayfield County, Wisconsin: groundwater flow direction (2017; 1:100,000 scale)
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
These linear features represent primarily horizontal groundwater flow direction in Bayfield County, Wisconsin. Groundwater flows from higher to lower water-table elevations, generally perpendicular to the contours of the water-table map (plate 1). The water table slopes away from groundwater divides (also shown on plate 1). There is also a vertical component of groundwater flow not illustrated on the map, which is typically downward near groundwater divides and upward where groundwater discharges to lakes and streams.The methodology and results are documented in an accompanying summary report available from the Wisconsin Geological and Natural History Survey.
Purpose:
These data accompany the Wisconsin Geological and Natural History Survey Open-File Report 2017-02. Plate 1 of this report, "Generalized water-table elevation map for Bayfield County, Wisconsin," was developed using information from wells in Bayfield County, previously published maps of surficial and bedrock geology, and an existing groundwater flow model. Well information was also used to evaluate characteristics that can influence the well’s susceptibility to contamination originating at or near the land surface. The compilation and interpretation of data was intended to support discussions and decisions surrounding land use in Bayfield County.
Four datasets accompany the report: water-table contours, groundwater divides, groundwater flow lines, and well points. This dataset consists of the groundwater flow lines.

This project was completed by the Wisconsin Geological and Natural History Survey (WGNHS), UW-Extension, with support from the Bayfield County Health Department.
The well database compilation, used in the report and to help develop the water table map, was completed by Stephen Mauel, GISP, a GIS Specialist at the Wisconsin Geological and Natural History Survey (WGNHS): Mauel, S.W., Pederson, E., Schoephoester, P.R., 2010, Geodatabase of water wells in Bayfield County, Wisconsin: Wisconsin Geological and Natural History Survey geodatabase.
Well data are from Well Construction Reports (WCRs) submitted to the Wisconsin Department of Natural Resources mainly between 1988 and 2010.
Water table contours were developed using a groundwater model from the following report: Fehling, A.C., Bradbury, K.R., Schoephoester, P.R., Mauel, S., Leaf, A.T., Hunt, R.J., Juckem, P.F., and Pruitt, A., In Review, Characterization of groundwater resources in the Washburn/Great Divide Unit of the Chequamegon-Nicolet National Forest, Wisconsin: Wisconsin Geological and Natural History Survey Technical Report X.
Water table contours for two agricultural regions of Bayfield County were completed for a previous project: Gotkowitz, M.B., and Li, Y., 2016, Groundwater and wells in agricultural regions of Bayfield County, Wisconsin – Report to the Large-Scale Livestock Study Committee: Wisconsin Geological and Natural History Survey Technical Report 2, 13 p.
