About this episode

The episode discusses the impact of algae blooms and environmental changes on the Yahara Lakes with experts from Clean Lakes Alliance and the Center for Limnology.

The Yahara Lakes define this region where people flock to the water year-round for recreation. But algae blooms, Madison’s continued growth, and the warming planet are changing the makeup of our waterways. On today’s pledge drive edition of A Public Affair, Douglas Haynes is in conversation with James Tye of Clean Lakes Alliance and Jake Vander Zanden of the Center for Limnology about the 2025 State of the Lakes report, the annual checkup of the Yahara watershed.
