Lake Wingra is home to thousands of plants and animals. Because of its unique location in the middle of Wisconsin’s capital, Lake Wingra is forced to adapt to a number of human induced elements. Because of Madison’s population density and urban sprawl, run off from fertilizers, car exhaust, industrial waste, and garbage have altered the special environment of Lake Wingra. In response, the Lake has changed over the years. Students at Edgewood College have become concerned of these changes, and as a result, a number of interesting research studies on the effects of human pollutants has been conducted. These studies can be accessed by browsing the links below. The following is from the Department of Natural Science at Edgewood College ( http://natsci.edgewood.edu/wingra/wingra_watershedmgmt.htm ).
