We work with multiple partners to ensure the conservation of Big Green Lake and its watershed with a focus on water quality. We envision a clean, healthy lake that fulfills the needs of future generations for living, playing, and working.
The waters of Big Green shape the identity of the Green Lake community. They tie past generations to generations yet to come. Since Green Lake’s “retention time” (the time it takes one drop of water to exit the lake once it enters) is 21 years, we have to act now to ensure a cleaner, healthier lake for future generations.
