These data were produced as part of a project to inventory and assess Columbia County's groundwater resources. Information about regional hydrologic conditions can help guide planning decisions concerning land use and water resources. The groundwater divides in Columbia County can be used to identify the areas in which shallow groundwater flows toward particular stream systems. Location of the divides is approximate as they 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.
These data depict shallow groundwater divides in Columbia County, Wisconsin. Groundwater flows though the subsurface in response to gravity, from areas of higher water-table elevation along a groundwater divide, to areas of lower water-table elevation. Groundwater divides in Columbia County are along or relatively close to major surface-water divides.
The map data are a regional interpretation of the water table, intended for presentation at a scale of 1:100,000, and may not be sufficient for use at a site-specific scale.
The Columbia County Groundwater Project is a joint project of the Columbia County Land and Water Conservation Department; the United States Geological Survey; and the Wisconsin Geological and Natural History Survey (WGNHS), a unit of the University of Wisconsin-Extension.
