Title:
Saturated thickness in feet of unconsolidated materials (glacial deposits) in the Washburn/Great Divide Unit of the Chequamegon-Nicolet National Forest, Wisconsin
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
This dataset consists of contour lines showing the saturated thickness of unconsolidated materials, defined as distance in feet from the water table to the top of bedrock, denoted by the attribute field “contour.” The dataset was created by subtracting the estimated bedrock surface from the water table. The bedrock surface was interpreted using a combination of well construction reports, geophysical surveying, and previously published data on bedrock outcrops; the water table was exported from a steady-state regional groundwater flow model. The methodology and results are documented in an accompanying summary report available from the Wisconsin Geological and Natural History Survey. This dataset was developed from data of varying map scales and may not be accurate for site-specific applications.
Purpose:
This dataset was produced as part of a project to assess groundwater resources across the Chequamegon-Nicolet National Forest. Groundwater is an important resource for the forest, and a more comprehensive understanding of this resource can help guide land management decisions. Saturated thickness maps show the variability and magnitude of glacial aquifer thickness, which influences groundwater flow and availability. Combined with geologic and water-table maps, saturated thickness maps can be used to develop a conceptual framework for the hydrogeologic system. The datasets produced as part of this project are divided by location into four groups, corresponding to the four main National Forest Units: Medford, Nicolet, Park Falls, and Washburn/Great Divide. This dataset is located in the Washburn/Great Divide Unit.

Data_Quality_Information:
Completeness_Report:
The interpreted saturated thickness contours depend on the data quality of both the interpreted bedrock surface (WGD_BedElev_WGNHS_2016) and the model-simulated water table (WGD_WatTabGFLOW_ WGNHS _2016). The bedrock surface is based on available point data of varying quality and scale. There are large areas of little or no data. The accuracy of the map is unknown in these areas, whereas the accuracy increases with the concentration of data points. The water table was exported from a two-dimensional, regional groundwater flow model. Areas near surface water features and areas with local subsurface variability not captured in the model may not be represented well. The performance of the model compared to known head and baseflow measurements is included in the report. The accuracy of the results is not known in areas with sparse data points. The saturated thickness contour interval was selected to reflect the interpreted accuracy of the input data.
