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.
Welcome to the Great Lakes Coastal Wetlands online explorer, provided by Michigan Tech Research Institute (MTRI). Through a binational collaborative project between Canada and the United States, the team has been working to better measure and map coastal wetland features and hydrologic changes through time at fine resolution. Several remote sensing derived products have been developed for monitoring wetland type, extent and inundation of Great Lakes coastal wetlands.
This report provides an assessment of progress toward harmonization of prohibited AIS in Great Lakes states and provinces over the last decade, including a comparison of current regulated species lists across the Great Lakes basin to regulations that existed in 2012, the first time that a comprehensive list of all regulated aquatic invasive species was compiled for the basin.
The Great Lakes Regional Water Use Database provides comparable water use information on withdrawals, diversions and consumptive uses. This database supports the states and provinces in implementing Article 4 of the Great Lakes-St. Lawrence River Basin Water Resources Compact and Article 301 of the Great Lakes-St. Lawrence River Basin Sustainable Water Resources Agreement.
