U.S. Army Corps of Engineers (USACE) is working in collaboration with other Great Lakes stakeholders interested in using wetlands for phosphorus reduction, including The Nature Conservancy, Ducks Unlimited, academic institutions, and other federal agencies. Research and an engineering evaluation will inform decision-making about the potential for treatment wetlands to be a significant part of controlling phosphorus from agricultural runoff in the Great Lakes.

Upon completion of the current research and monitoring effort, which will be paired with spatial analysis and modeling to identify optimum sites for wetlands, USACE and partners anticipate construction of new full-scale wetland sites to test and demonstrate the potential of phosphorus-optimal wetlands starting in 2019.
