In June, 2003, DEQ conducted a Surface Water Quality Bio-Assessment of several sites in the Bean Creek watershed to determine the impact of Confined Animal Feeding Operations on aquatic life. Aquatic biologists identified and counted fish, and identified and counted aquatic insects.  More information on the final report can be found here.

As a result of the biosurvey, two streams in the Bean Creek Watershed were added to Michigan's 303(d) list of impaired waters -- Durfee Creek, for low Dissolved Oxygen; and Medina Drain because of poor macroinvertebrate communities, excess nutrients.
