Land use in the watershed is primarily agriculture and residential, though industrial ares do exist in the urban areas of Green Bay and the north side of Appleton. Aquatic life habitat and macroinvertebrate communities in these headwaters are generally fair to poor in condition. Sediment and phosphorus loading from upland agricultural fields are the major sources of nonpoint pollution in the watershed. Super Value Stores Inc. Information on each facility is presented in Table 7 . Apple Creek Apple Creek, a 24-mile creek, is usually dry except for scattered pools near road crossings and toward the mouth of the river where it drains into the Fox River.
Bottom materials are silt, rubble and gravel, with few boulders.
As many streams in Brown County, this one is plagued by erosion. Cattle pasturing along streambanks and hills has caused heavy erosion and no vegetation. Macroinvertebrates indicate fairly poor water quality. Nonpoint source pollution, point source pollution and urban stormwater runoff singly or in combination cause sedimentation, low dissolved oxygen levels, all of which contribute to poor water quality. Dissolved oxygen and temperature were monitored to document swings in DO due to external factors like rain or plants.
