The Great Lakes Water Quality Agreement (GLWQA), signed by Canada and the United States, is a commitment to protect the waters of the Great Lakes. It was most recently updated in 2012. Annex 4 was formed to manage phosphorus concentrations and loadings (and other nutrients if warranted) in the Great Lakes.

The United States and Canada adopted phosphorus load reduction targets to combat Lake Erie algal blooms. 

The Great Lakes Panel on Aquatic Nuisance Species coordinates education, research, management and policy efforts to prevent new AIS from entering the basin and to control and mitigate those AIS populations already established. The Great Lakes Panel is one of six regional panels that report to the federal Aquatic Nuisance Species Task Force, which coordinates AIS efforts on a federal level. 

Through the Aquatic Invasive Species Annex of the 2012 Great Lakes Water Quality Agreement, the United States and Canada have committed to “… contribute to the achievement of the General and Specific Objectives of this Agreement. Through this Annex the Parties shall establish a binational strategy to prevent the introduction of Aquatic Invasive Species (AIS), to control or reduce the spread of existing AIS, and to eradicate, where feasible, existing AIS within the Great Lakes Basin Ecosystem.”
