Kaskaskia Region

In 2009, funding allowed for the selection of the Kaskaskia Region as the third priority area for water supply planning efforts. The Kaskaskia Region (map)was defined by the Illinois Department of Natural Resources (IDNR) to include the entire Illinois counties of Bond, Christian, Clay, Clinton, Coles, Cumberland, Douglas, Effingham, Fayette, Jasper, Marion, Montgomery, Moultrie, Randolph, Richland, Shelby, Washington, and Wayne and the portions of Macoupin, Madison, Monroe, and St. Clair counties that are located within the Kaskaskia River watershed. Four of these counties (Clay, Cumberland, Jasper, and Richland) are located entirely outside of the Kaskaskia watershed; however, water from the Kaskaskia watershed is purveyed to portions of Clay County, and it was considered that potential exists that the other three counties might receive Kaskaskia water in the future. The focus of this study is on the water supplied from sources within the Kaskaskia watershed. There are limited groundwater resources within the watershed. As a result, the study effort highlights the surface-water resources of the region, with particular interest on the two federal reservoirs, Lake Shelbyville and Carlyle Lake, and water supply allocations from these two reservoirs.

Primary Publications

Kaskaskia Basin & Vicinity 2050 Water Supply Assessment and Recommendations (Kaskaskia Basin Water Supply Planning Committee) (pdf ~1.4mb) -- The Comprehensive Evaluation and Plan for the Regional Water Supply of the Kaskaskia River Basin through 2050 is aimed at assessing the water supply and the water demands within the Kaskaskia Basin through the year 2050. This includes analyzing and evaluating various scenarios involving potential changes in water demands and the water supply, including federal and community reservoirs, and identifying impacts from the specific scenarios.
Future Water Demands and Coal Development Potential in Kaskaskia River Basin in Illinois (Illinois Clean Coal Institute) (pdf ~3.4mb) -- This study analyzed the existing water demands as well as future water-demand scenarios for all major user sectors in the 22-county regional planning area that includes the Kaskaskia River basin in Southwestern and Central Illinois. The objective was to determine future water demands during the period from 2010 until 2050 and compare the sectoral demands with the potential water needs for coal development and processing and thermoelectric generation within the study area.
Water Supply Assessment for Kaskaskia River Watershed Development: Phase 1 Technical Report (Illinois State Water Survey, Office of Water Resources) (pdf ~3.4mb) -- This document was prepared for the Kaskaskia Basin Water Supply Planning Committee to aid their development of a plan for meeting the future growth of water supply demands within the basin. It contains background information to provide an overview of management criteria and an understanding of the constraints and policies used in conducting analyses and making decisions concerning water use within the Kaskaskia Basin.

Additional Publications and Information

The first phase of the Kaskaskia study effort, funded by the Illinois Department of Commerce and Economic Opportunity through the Illinois Clean Coal Institute, produced the following two reports:

Future Water Demands and Coal Development Potential in Kaskaskia River Basin in Illinois

Water Supply Assessment for Kaskaskia River Watershed Development: Phase I Report


Archived Material and Presentations

The second phase of the study effort (2011-2012), funded by the IDNR, supports the meetings of the Kaskaskia Basin Water Supply Planning Committee and the additional water resource evaluations by the ISWS for meeting a range of future water demand scenarios.
