In 1978, the Wisconsin Legislature committed to protecting water quality by enacting the Nonpoint Source Water Pollution Abatement Program. Through this program, cost-share money is provided within priority watersheds to control sources of nonpoint pollution. Most of the cost-share dollars for rural watersheds have been used to implement barnyard Best Management Practices (BMPs) because barnyards are believed to be a major source of pollutants, most notably phosphorus. Reductions in phosphorus loads of as much as 95 percent have been predicted for the barnyard BMPs recommended for priority watersheds.
