Although previous publications by a number of agencies have contained considerable data, the need was expressed by Dr. Delyte W. Morris, President of Southern Illinois University, for a semi-technical publication which would combine and analyze available information on the water resources for the 17 southernmost counties. Extractions from previous publi• cations and references are used liberally to avoid duplication of detailed data. Secondly, this report is intended to help bring about greater understanding of hydrologic, meteorologic, and chemical data in an evaluation of water resources. It is hoped that this report will be of value for industrial development, in urban and regional planning, for recreational development, and to some degree for agricultural interests. 11 POTENTIAL WATER RESOURCES OF SOUTHERN ILLINOIS SUMMARY cooling towers, occur on the average 11 per cent of the hours during June, July and August.
