Abstract |
The water-quality surveillance program begun in 1983 to sample the open waters of Lakes Michigan, Huron and Erie (the middle Great Lakes) was continued in 1985. The principal objectives of the program were to determine the water quality of the three lakes, especially with regard to the concentration of nutrients in the open waters; to continue the program of annual sampling so as to provide data necessary for detection and evaluation of both trends and annual variability in water quality; and to provide data relevant to the ongoing verification and modification of the nutrient-based eutrophication models that have been developed in conjunction with previous Great Lakes surveillance. The major findings of the 1985 survey are summarized below; the details of the analyses and statistical summaries (SAS, 1982 and 1985) and tables presenting the results are included in later sections. |
