The major objective of the project was to assess the present condition of the lake and recommend an integrated protection/mitigation plan for the lake and its watershed on the basis of this evaluation. The diagnostic study was designed to delineate the existing water quality problems and other factors affecting the lake's recreational, aesthetic, and ecological qualities; to examine the causes of degradation, if any; and to identify and quantify the sources of nutrients and any pollutants flowing into the lake. The diagnostic-feasibility study was funded 70 percent by the U.S. Environmental Protection Agency (USEPA) under the Clean Lakes Program (section 314 of the Clean Water Act), with the remaining costs (30 percent) being contributed by the city of Hammond, IN. Located in Lake County in the far northwest corner of Indiana, Lake George sits in an industrial area within the urbanized greater Chicago region. Since the mid-1970s, a 240-acre area including Lake George has been owned by the Robertsdale Foundation, the financial support organization for Calumet
