Description:Achieving greater efficiency in programs to reduce the impacts of agricultural nonpoint pollution is an important interest in the Great Lakes basin, especially with respect to enhancing habitat for sport fish species. One aspect of efficiency is `targeting'--taking abatement actions where they are most cost-effective. This study develops a pollution-risk management framework that combines farm management models, pollutant transport models, weather event simulations, and fish habitat models. Results suggest that (1) a targeted program can achieve significant improvements in habitat quality and reliability at reasonably low cost, and (2) erosion or sediment control are poor ways to achieve high levels of habitat quality and reliability where soluble pesticides are the limiting pollutants.
