Office of the Great Lakes
Office of the Great Lakes
As the Great Lakes State, Michigan upholds the highest standards for protecting, restoring, and sustaining the Great Lakes, the world’s largest freshwater resource. The Office of the Great Lakes (OGL) is a leader in developing policy and implementing strategic programs to protect, restore, and sustain the Great Lakes watershed. The office collaborates with partner organizations to support sustainable water use and development of Great Lakes maritime resources; support vibrant and resilient communities; foster water stewardship; and advance science, research, and policy to solve the next generation of water challenges.
The Michigan Legislature created the office in 1985 under the Great Lakes Protection Act.
Great Lakes and Freshwater Week, May 31 - June 8, 2025
Each year, Michigan proclaims this week to raise awareness of the Great Lakes and Michigan’s inland waterways and groundwater. It’s a time to reflect on the interconnectedness between Michiganders and the matchless water resources around us. By raising awareness, we will inspire people to protect and be champions of the Great Lakes and fresh water.
Our call to action is for residents around the state to learn about, enjoy, appreciate, and safeguard this vital resource for current and future generations. How will you celebrate connections and protect Michigan’s Great Lakes and fresh water? Share your photos, actions, and stories on social media with #MiGreatLakesWeek.
