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. Ashwaubenon Creek Ashwaubenon Creek, a 15-mile sluggish, hard water stream flowing through agricultural and residential Brown County.
Bottom materials consist of rubble, gravel and silt.
In the agricultural portion of the stream the stream banks and hills are bare and erosion heavy due to cattle pasturing. In the residential area the stream is filled with litter an debris. 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. During mid-summer low flow conditions, most of Dutchman Creek and all of its tributaries dry up.
