Abstract
A survey was done on Otsego Lake in Otsego County, MI to determine its trophic status. Factors such as a very shallow average depth, high Shoreline Development Index, strong human influence and close vicinity to the road increase its chances of becoming a more productive eutrophic system. We looked at chemical, biological, and physical characteristics to determine the impact of cultural eutrophication (i.e., organic pollution) on this system. Many residents have recently complained about the presence of an unknown ""floc"" within the water column. From our data we have determined that this floc is most likely suspended organic matter due to the massive growth of potamogeton in the lake. Furthermore, we found the status of the lake to be ultimately mesotrophic, but verging upon eutrophy. However, if current trends continue the likelihood that the lake will become eutrophic will indefinitely increase.Subjects
