- Title:

Model-simulated water table elevation contours (feet) 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 model-simulated water table elevation in feet above mean sea level, denoted by the attribute field “contour”. Two groundwater flow models were created using the analytic element code GFLOW, and the resulting simulated contours were combined into one coverage to create this dataset. The methodology and results are documented in an accompanying summary report available from the Wisconsin Geological and Natural History Survey. The groundwater flow model is a two-dimensional regional model 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.
Water table maps show the elevation of the water table in feet above mean sea level. The water table was simulated by a regional groundwater flow model developed for this project. The simulated water table is useful for identifying groundwater elevation and regional flow direction, especially in areas with sparse data points.
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.

-
- Completeness_Report:
-
The water table contours in this dataset were 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 head and baseflow measurements is included in the accompanying report.
