The lower third of Green Bay and the Lower Fox River were intensively studied. Seven surveys of the Bay were carried out between September 1973 and September 1974. Over 40 stations were sampled for 15 different chemical and physical chemical and physical parameters. In addition, plankton samples were taken and general groupings and counts were made. Nearly 5,000 data points were generated and inserted into the STORET system. The surveys revealed algae blooms over the entire study area. Nitrogen forms showed fluctuations over 3 orders of magnitude that may be relatable to nitrogen-fixing algae. Phosphorus concentrations were more stable than nitrogen concentrations, but appeared to decrease in correspondence to blue-green nitrogen-fixing algae. Dissolved oxygen concentrations in the Bay were generally acceptable except during the winter survey. The February survey revealed critical dissolved oxygen levels over a 50 sq. mile area north of Point Sable. Computer models of the Lower Fox River and Green Bay were developed and used to evaluate the effect of the final limits for the present discharge permits at all point source discharges on the water quality, specifically dissolved oxygen.
