This is one in a series of reports documenting background information for the development of a water quality control program for Lake Michigan and its drainage basin. For planning purposes the Lake Michigan Watershed has been subdivided into appropriate tributary drainage basins. For the purpose of projecting water uses and waterborne waste loads for these subbasins and in order to develop relationships among water uses, waste loads, population and economic development, information has been gathered on present conditions and past trends concerning population and economy.
