LANSING, Michigan —Today, the Michigan Department of Environment, Great Lakes, and Energy (EGLE) released the 2025 Michigan State of the Great Lakes Report. The annual report explores major accomplishments, issues, initiatives, and challenges related to the health and sustainability of our Great Lakes – the world’s greatest surface freshwater system. 

The 2025 report focuses on how individuals, communities, organizations, universities, tribes, and governments unite around the waters, ecology, and economy of Michigan’s Great Lakes.  

“Michiganders share a remarkable privilege – and responsibility – to protect and sustain our water resources great and small. Our lakes, rivers, and groundwater drive our economy and shape our way of life,” said EGLE Director Phil Roos. “The 2025 State of the Great Lakes Report underscores the progress we’ve made, the challenges that remain, and the power of collective action. I believe it will inspire continued commitment and innovation.” 

By statute, EGLE’s Office of the Great Lakes (OGL) prepares and submits the report each calendar year to the state Legislature on behalf of the Governor. The report is also posted online along with recent years’ editions. 

“This year marks the 40th anniversary of the office created in statute by former U.S. Ambassador and Michigan Governor James Blanchard with the recognition that the Great Lakes are central to our way of life, our communities, Michigan’s economy, and our heritage,” said EGLE Great Lakes Senior Advisor and Strategist Emily Finnell, who leads the OGL. “Our work to develop state and regional policies, implement programs, collaborate with partners, and steward our Great Lakes today shapes the health, resilience, and sustainability of these waters for generations to come. This work is our greatest challenge and our greatest opportunity.” 

This year’s report highlights activities affecting numerous communities and every Great Lake bordering Michigan. It addresses topics including environmental cleanup, waterfront restoration and revitalization, invasive species, Michigan’s flora and fauna, and growing Michigan’s blue economy. Here’s a cover-to-cover list: 

• Michigan’s OGL and its mission to lead policy development and strategic implementation of programs to protect, restore, and sustain the Great Lakes and grow the next generation of water stewards at home and abroad after 40 years.
