| Abstract |
A survey is made of current and historical information relating to the quality of the waters of Green Bay, Lake Michigan. The steady decline in water quality over the last four decades is documented. A historical shift in fish production from high quality native species to low quality exotic species has occurred. Increasing areas of the Bay exhibit low oxygen levels. In winter, under the ice, low oxygen levels now extend into the Bay as far as 40 kilometers. Nutrient loads have caused the areas where eutrophic conditions exist to increase. These and other factors have led to a dislocation of recreational use. Documentation of the expected reduction in pollutant loads due to present control strategies is also provided. Field studies performed in this program indicate slight improvements in bay water quality over recent years. |
