From the smaller lakes dotting our landscape to the Great Lakes encircling us – and don’t forget our rivers, streams, and aquifers – natural waters are foundational to the people of Michigan. Any day can be a lake day in Michigan, but Thursday, Aug. 27, is the official World Lake Day, declared by the United Nations (U.N.) General Assembly and dedicated to preserving, celebrating, and sustainably managing the world’s lakes.  

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) and its Office of the Great Lakes (OGL) are joining communities worldwide to celebrate World Lake Day by spotlighting the critical importance of the world’s lakes and highlighting the vital role of youth education in sustaining the world’s freshwater legacy. 

On World Lake Day and every day, the OGL invites all Michiganders to spend time by water, reflect on the wonders of our Great Lakes State, and act to protect these vital resources. Action can be as simple as picking up trash or joining an organized cleanup, swimming or wading, boating or fishing, reading a book or article, watching a video or webinar, or supporting organizations advancing research or stewardship. Opportunities to engage include:   

• Enjoying the outdoors in and around Michigan waterways safely and sustainably by following tips for responsible recreation. Spend time paddling on Michigan Water Trails, going birding, or identifying wildlife in your neighborhood. Learn to identify aquatic invasive species through MI Paddle Stewards. Share photos and reflections on EGLE’s Facebook page or on personal social media accounts using the hashtag #WorldLakeDay. 

• Registering to join the “World Water Day: Many Lakes. One Mission” webinar, 9-10:30 a.m., Aug. 27, sharing powerful lake stories, youth-led action, and science-based solutions across continents. This live celebration, co-hosted by AquaVox and Water Solutionaries, will bring together leaders, experts, educators, and community members including Emily Finnell, head of the OGL, to highlight the importance of lakes in sustaining life, biodiversity, and livelihoods around the world.  

• Checking out water-related informational webinars on EGLE’s webinar series, Stewarding the Great Lakes, and past events and recorded webinars webpages.  

• Settling in with a “beach read,” like one of the Library of Michigan’s more than 200 titles related to the Great Lakes, a Great Lakes Reads 2026 selection from the Library of Great Lakes, or an annual Michigan State of the Great Lakes report from the past 40 years.  

• Taking a class, joining an event, or reading about Great Lakes Literacy principles to deepen your understanding of how you and the Great Lakes affect each other.  

• Volunteering in your community: Connect with your local Michigan watershed organization, report suspicious algae to EGLE to help track the appearance of harmful algal blooms, or create or join a cleanup effort on your own or with a tool like Alliance for the Great Lakes’ Adopt-a-Beach. 

• Protecting our inland lakes and streams by getting involved in one of three volunteer opportunities to collect water quality and habitat data through the Michigan Clean Water Corps (MiCorps): the Volunteer Stream Monitoring Program, Volunteer Stream Cleanup Program, and Cooperative Lakes Monitoring Program.  

Youth-focused educational opportunities include: 

• Exploring current opportunities and activities through the From Students to Stewards Initiative to grow future water stewards and leaders and help students from elementary through high school learn about the Great Lakes, Michigan’s watersheds, and actions people can take to steward water resources across the state.  

• Learning about Michigan programs and educational resources, including the MiSTEM Freshwater Literacy and Stewardship playbook, that support “3P” learning (based on places, projects, and problems) and promote stewardship of Michigan's waters, watersheds, and environment. 

• Deepening lessons and learning with EGLE Classroom and the Center for Great Lakes Literacy Resource Library, both of which support teachers, students, and parents in environmental education. 

About World Lake Day 

The U.N.’s designation of World Lake Day reflects growing international recognition of freshwater lakes as critical resources and defenses against the worst impacts of climate change. The observance date, Aug. 27, commemorates the first World Lake Conference in 1984, in Shiga Prefecture, Japan. Shiga – home to Japan’s largest freshwater body, Lake Biwa – has a sister state relationship with Michigan because of their shared commitments to lakes. 

World Lake Day is a global reminder of the importance of lakes to communities, economies, the environment, and quality of life. In Michigan, where the Great Lakes are central to our identity, the day reinforces a shared commitment to preserve these waters for future generations.
