This report summarizes data contained in five lake-specific volumes which describe and quantify, as appropriate, the U.S. Great Lakes Basin's geology, soils, minerals, climate, surface and ground water, vegetation, wildlife, and economic and demographic characteristics. It provides an overview of available information on waste disposal operations, lakeshore and riverbank erosion, high-density non-sewered residential areas, and recreational land uses as well as materials application of agricultural chemicals, fertilizers, lime, animal wastes, and salts on highways. Future trends and projections are shown.
