LOCATION AND EXTENT OF STUDY AREA

The central Wisconsin River basin is the middle part of the entire Wisconsin River basin. The basin is about 5,050 square miles in area, and extends about 110 miles south from Merrill to Wisconsin Dells. The basin includes all or parts of the following counties: Adams, Clark, Columbia, Jackson, Juneau, Langlade, Lincoln, Marathon, Marquette, Monroe, Portage, Sauk, Taylor, Waushara, and Wood.

PURPOSE AND SCOPE

This study provides a background of hydrologic knowledge suitable for use by water-resource planners and managers, and it provides a framework for more detailed water-resource studies in the future. Specifically, the purposes of this report are to: (1) Describe the geologic and hydrologic environments of the central Wisconsin River basin. (2) Describe the water resources of the central Wisconsin River basin including their sources, uses, quality, interrelationships, availability, and behavior within the basin environment. Much of the information in this report has been generalized to allow presentation in the atlas format. Liberal use was made of available data from many sources and interpretations from published reports. Additional material was collected and analyzed to allow a balanced presentation on water resources and the physical environment. This study is part of an investigation of the water resources of the major river basins in Wisconsin. The completed basin studies and those being studied are shown on the cover envelope. The information in this report should be adequate for the broad aspects of planning water-resource development and management. However, individual problems and water needs will require more specific information than is given in this report.
