About Runoff Management

When water from rainfall or melting snow flows across the landscape, it washes soil particles, bacteria, pesticides, fertilizer, delta image pet waste, oil and other toxic materials into our lakes, streams, and groundwater. This is called "nonpoint source pollution" or "polluted runoff." Nonpoint source pollution comes from a diverse number of activities in our daily lives including fertilizing lawns and farm fields, driving and maintaining our cars, constructing buildings and roads, plowing our fields for crops, and maintaining our roads in the winter.

Urban and rural nonpoint pollution is the leading cause of water quality problems in Wisconsin, degrading or threatening an estimated 40 percent of the streams, 90 percent of the inland lakes, many of the Great Lakes harbors and coastal waters, many wetland areas and substantial groundwater resources in Wisconsin. *

Polluted runoff contributes to habitat destruction, fish kills, reduction in drinking water quality, harbor and stream siltation, and a decline in recreational use of lakes. Through both voluntary and regulatory programs, DNR Runoff Management Section Staff work to decrease the impact of polluted runoff upon the water resources of Wisconsin.

A synopsis of the Runoff Management administrative rules is contained in Wisconsin's Runoff Rules. [PDF 459KB]
