Rock River Basin Groundwater
Project Number: 9KH67
Project Chief: Paul F. Juckem
Project Topics: ground-water planning
Cooperators: Rock River Coalition
Period of Project: October 2006 - September 2009
An analytic element (AE) ground-water-flow model of the 3,800-square-mile Rock River Basin was being developed by the U.S. Geological Survey in cooperation with the Rock River Coalition and many of the communities within the basin.
Communities in the Rock River Basin, particularly those with municipal water supply systems, make decisions that affect their ground-water resources every day. To assist with resource management, an analytic element (AE) ground-water-flow model of the 3,800-square-mile Rock River Basin was developed by the U.S. Geological Survey in cooperation with The Rock River Coalition and many of the communities within the basin.
The development of this model leveraged existing data and ground-water flow models in Dane County, Rock County, and the South East Wisconsin Regional Planning Commission region. These existing models are of different types (analytic element and finite difference), vintage, and scales, and were constructed with various objectives. However, through a step-wise approach, in which previous simulation results are used to guide contemporary model design and data collection, the information supporting these existing models was incorporated to develop a unified hydrogeologic framework for the Rock River Basin.
The basin-scale model provides water suppliers and users with an important tool to understand the regional flow of ground water in the basin, its interaction with rivers, lakes, and wetlands, and its sensitivity to historical and future water-use. In addition, the hydrogeologic framework developed through this step-wise approach can provide a foundation for future simulations of detailed local-scale ground-water issues in the Rock River Basin.
The Rock River Coalition, our cooperator, raised funds to support this effort from 38 partners (cities, counties, associations, citizens, and private businesses).
