This bill, known as the Great Lakes Restoration Initiative Act of 2025, seeks to reauthorize and extend funding for the vital Great Lakes Restoration Initiative (GLRI). It amends the Federal Water Pollution Control Act to ensure continued financial support for environmental protection and restoration efforts across the Great Lakes region. The legislation specifically allocates a substantial sum of $500,000,000 annually for the program. This significant funding is designated for a five-year period, covering fiscal years 2027 through 2031 , to address various ecological challenges and support ongoing restoration projects in the Great Lakes.
