Abstract:

Dissolved oxygen depletion in the lower Fox River (Wisconsin) and Green Bay (Lake Michigan) have historically been tied to discharges of organic matter from municipal waste treatment plants and the pulp and paper industry. Despite reductions in those discharges, oxygen depletion occurs over a wide area of the bay. Quantification of tributary loads, primary production and biochemical oxygen demand in the water column, and sediment oxygen demand points to nutrient enrichment and resultant cultural eutrophication as the cause of hypolimnetic oxygen depletion.
