WHAT WE DO
To safeguard Green Lake by improving its water quality, protecting it from critical threats, and accelerating its return to a clean lake.

A healthy, resilient watershed that sustains a clean, restored Green Lake.
ABOUT THE GLA
The Green Lake Association is a science-driven nonprofit dedicated to protecting Wisconsin’s deepest natural inland lake. Through phosphorus reduction, invasive species prevention, and watershed restoration, the GLA is working to improve water quality and build long-term resilience. By engaging volunteers, partnering with local schools, and fostering hands-on lake experiences, we’re strengthening the community’s connection to Green Lake and inspiring generations of stewards
to care for it.
“The waters of Green Lake shape our identity. They tie us to past generations,
and generations yet to come.”
