Protecting Green Lake doesn’t happen in isolation.

Recently, GLA’s Director of Programs, John Strauser, connected with lake leaders from Geneva Lake and North Lake to exchange ideas, share lessons learned through science-based research and action, and discuss goals for the future.

Every lake faces its own unique challenges, but there is tremendous value in learning from others working toward the same goal: healthier lakes for generations to come.

As Lynn Grayson of the Geneva Lake Association shared, “Geneva Lake and Green Lake have much in common, sharing similar legacies to preserve and protect our lakes so they can continue to be enjoyed by future generations.”

By sharing what’s working, talking openly about challenges, and building relationships with others doing this important work, we’re strengthening not only our efforts here at Green Lake, but lake conservation across Wisconsin.

*UPDATE AUGUST 28, 2026*

The Green Lake Association has confirmed the presence of microcystin toxins at Dodge Memorial County Beach during our weekly blue-green algae monitoring.

While our team did not observe visible signs of a blue-green algae bloom, testing detected the presence of microcystin toxins. Based on these results, the Green Lake County Public Health has issued an advisory for swimming at Dodge Memorial County Beach until conditions improve. We strongly encourage everyone to avoid contact with the water in the affected area.

Blue-green algae (cyanobacteria) can produce toxins that are harmful to people, pets, and wildlife. Please:

-Avoid swimming, boating, fishing, and other water activities in areas with visible algae scum, streaks, or discolored water.
-Keep children and pets away from affected areas.
-Rinse off thoroughly with clean water if you come into contact with suspicious water.
-Report any new sightings of unusual water conditions to the Green Lake Association.

Our team will continue monitoring conditions through regular visual assessments and toxin testing and will share updates as conditions change. This week’s results are an important reminder that toxins can be present even when there are no visible signs of a bloom. Because blue-green algae conditions can change quickly and vary from one area of the lake to another, we encourage everyone to remain aware of water conditions wherever they are enjoying Green Lake.

When in doubt, stay out.

Follow the Green Lake Association for the latest updates.

The National Weather Service is experimenting with a new inland lake wave forecast, and Green Lake is one of just 12 lakes included in the pilot program.

The forecast provides information about expected wave conditions, giving boaters another resource to consider when planning their time on the lake.

You can view the current forecast for Green Lake by selecting the lake on the National Weather Service’s inland lake wave forecast page:

*UPDATE AUGUST 21, 2026*

Good news heading into the weekend — all monitored locations around Green Lake are currently clear, with no active swimming closures or water quality advisories.

The Green Lake Association and our partners continue to monitor changing water conditions throughout the lake to help our community stay informed and enjoy Green Lake safely.

As always, conditions can change quickly. When in doubt, stay out if you notice discolored water, surface scum, or other signs of a potential blue-green algae bloom.

Enjoy the lake and have a safe weekend!

Protecting and improving Green Lake requires a community committed to coming together. Even small, day-to-day actions can have an impact on the lake.

Whether it's picking up pet waste, using the boat cleaning stations to prevent the spread of AIS, planting native plants, or sweeping grass clippings off the street and out of the storm drain, everyone has a role to play.

No one action will protect the lake on its own, but together, we can steward Green Lake for generations to come.

Maybe it started with a grandparent who brought you here as a child. Maybe it was a family tradition passed down through generations, a longtime friendship, a favorite summer memory, or a person who made Green Lake feel like home.

As part of our 75th anniversary celebration, our 75 Tribute Challenge invites you to honor the people who shaped your connection to this special place.

Now, you can explore those stories on our new virtual Tribute Wall. Read the names, memories, and connections shared by members of our community — and see the many different paths that bring us together around Green Lake.

But, who is part of your Green Lake story? Make a tribute gift in their honor or memory and add their story to our celebration. Your tribute can be a way to recognize someone who introduced you to the lake, created lasting memories here, or helped make Green Lake a meaningful part of your life.

Protecting and improving Green Lake is a shared effort. We're grateful to have a strong team of volunteers committed to doing just that.

This summer, Abby Faul joined the Green Lake Association as a Water Action Volunteer (WAV), helping monitor local streams throughout the watershed and contributing to the long-term health of Green Lake.

For Abby, volunteering is an opportunity to make a difference in the community she calls home.

"I have always been an advocate for the natural world, especially bodies of water," Abby shared. "I realized I can make a difference in my own community."

Thank you, Abby, for choosing to invest your time in protecting Green Lake. Volunteers like you help strengthen our understanding of the watershed and support a healthier lake for future generations.
