- Abstract:
-
These data depict the approximate locations of major groundwater divides in Calumet County, Wisconsin. A groundwater divide is similar to a surface-water divide, in that it is a ridge along the highest elevations of the water table. Shallow groundwater moves away from this divide, toward groundwater discharge areas. Groundwater divides are depicted in this dataset as wide and approximate areas because the location of the divide may change as the water table rises and falls in response to periods of rainfall and drought. Significant amounts of groundwater pumping from wells drilled near divides may also cause a divide to shift. The groundwater divides are useful to identify the areas in which shallow groundwater flows toward particular stream systems.
- Purpose:
-
These groundwater divides constitute a part of the data compiled and analyzed for the Calumet County Groundwater Project. The purpose of this project was to provide information pertinent to protecting the quality of groundwater resources in Calumet County.

-
The Calumet County Groundwater Project was funded by the Calumet County Board of Supervisors and the Wisconsin Department of Natural Resources Bureau of Drinking Water and Groundwater.
- Native_Data_Set_Environment:
-
These data are distributed as an ESRI ArcInfo Coverage in Interchange (.E00) format. The data were originally compiled in ESRI Geodatabase (version 9.0) format.

- Attribute_Accuracy_Report:
-
No user-defined attributes are present for the groundwater divide features.
- Logical_Consistency_Report: Polygon topology is present for the groundwater divides.
- Completeness_Report:
-
The depiction of the groundwater divides is approximate and is provided with this map for educational purposes; the divides illustrate the concept of groundwater flow toward discharge areas and surface-water features in the lowlands of the county. The elevation and location of the water table is difficult to identify with certainty along ridges in the uplands of Calumet County because there are few wells, wells that are present are completed with long open intervals, and surface streams tend to be seasonally present (ephemeral) and therefore not necessarily representative of the water table at that location.

-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
The groundwater divides are approximate and are presented for educational purposes. The degree of accuracy in their depiction is greater in areas where more water-table elevation control points (wells and perennial surface-water features) are nearby. Polygons of variable width are used to represent the divides to convey the approximate nature of locating the divide, which is more difficult to identify in some locations, and to illustrate that the exact location of the divide may change temporally.

1. The locations of water wells (represented by WCRs) were verified using base information from the DRGs.

2. For water wells with a verified location, land-surface elevations were estimated using a digital elevation model. Static depths to water reported on WCRs were subtracted from land-surface elevation estimates to estimate static water-level elevations in wells. Wells with water levels judged not representative of the water table were removed from the data set. Basis for removing water levels included uncertainty in x,y location of well, well open interval too deep to provide reasonable estimate of water table, well open interval not in uppermost aquifer, or estimated water-table elevation not consistent with nearby surface-water elevation.

6. The land-surface elevation at each vertex of the contours was estimated from a digital elevation model and compared to the elevation value of the contour; contours that exceeded land-surface elevation in areas not covered by surface-water features were edited on-screen to be below land-surface elevation. Contours were also edited to produce smoother curves.

7. Groundwater-divide polygons were digitized on-screen by identifying narrow "ridges" on the water-table surface that connect areas of highest water-table elevation. These features were plotted to 1:100,000-scale paper maps for verification and futher refinement.
