The deteriorated condition of the Lake Erie water resource, which had been well publicized during the 1960s contributed to the decline in the fishing industry and prohibited the full recreational use of the lake. Lake Erie, like many similar lakes exposed to cultural changes in the drainage basins, was undergoing accelerated eutrophication. A eutrophic lake is characterized by high algal production, turbidity, and at times, low oxygen content. These conditions combine to cause unpleasant tastes and odors, nuisance weeds on surface waters and on beaches, and a general degradation of the lakes ecosystem which leads to less desirable fish species in the lake. This study has established some of the important cause and effect relationships that have contributed to this accelerated eutrophication. The major pollutant responsible for the eutrophication, or advanced aging of the lake, is the nutrient, phosphorus. A specific plan has been developed which will lead to significant improvement in the quality of Lake Erie water and bring about a restoration of this vital fresh water resource. This management plan addresses the cause and effect relationships between land use in drainage basin and the level of phosphorus concentrations in the lake. The implication of the findings is that land management will be equally important as municipal and industrial wastewater renovation in the development of an overall plan for the reduction of phosphorus loadings to Lake Erie.
