A retrospective examination of water quality and habitat trends in the Upper Midwest show that landscape scales changes –such as crop conversion, drainage and fertilizers—have had profound, long-term effects on lakes, rivers and many associated upland species.    What are the recent trends, and how do their connection to changes over the past century help predict how to implement best management practices and policies that will meet our water quality standards in the future.  We have to assess the question:  Are we on the path to clean water and productive habitat while maintaining agricultural profitability---what will it cost and how can we pay for it?
