Following a robust binational science-based process and an extensive public consultation, the U.S. and Canada adopted new phosphorus reduction targets for the western and central basins of Lake Erie in 2016. The federal governments, states, and province of Ontario worked to develop strategies to meet these agreed-upon targets and reported them in Domestic Action Plans (DAPs). After receiving feedback from stakeholders, including public comments, the DAPs were finalized in 2018.
