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.
This report describes the following work of the Illinois State Water Survey, funded by the Illinois Clean Coal Institute:
Retrieval and summation of existing information regarding surface water and groundwater availability in the region. This report of existing information will also include information provided by the Illinois Department of Natural Resources-Office of Water Resources (IDNR-OWR) addressing the water supply storage and allocations from Carlyle Lake and Lake Shelbyville.
Development of surface and groundwater hydrologic models to simulate the hydrology of the Kaskaskia River watershed, water levels in the federal reservoirs, and selected local groundwater resources. Specific models developed include:
a Streamflow Accounting Model,
a Watershed Simulation Model and Reservoir Routing Models, and
a set of Groundwater Flow Models.
Major portions of this report deal with a summary of existing information. The models developed in this study will be applied to water use planning scenarios in the ongoing Phase II effort funded by the IDNR-OWR. Only limited results are available for inclusion in this report.published or submitted for publicationis peer reviewe
