The Great Lakes Governors established a list of nine priorities to guide the restoration and protection of the largest single source of fresh surface water in the world, the Great Lakes.

The Great Lakes St. Lawrence Governors & Premiers (GSGP) lead the protection of the world's largest supply of surface fresh water. Through the landmark Great Lakes—St. Lawrence River Basin Sustainable Water Resources Agreement and the companion Water Resources Compact, we provide the legal and policy framework for eight States and two Provinces to manage and protect our water resources. By coordinating regional implementation and fostering wise water use, we ensure the Basin remains healthy to sustain both our environment and the region's competitive economic advantage.

The Great Lakes and St. Lawrence Governors’ and Premiers’ Aquatic Invasive Species Task Force works to stop the introduction and spread of aquatic invasive species (AIS) into the Great Lakes St. Lawrence River Basin.
