After an incredible first year, we are thrilled to bring back Freshwater Discovery Day on July 30th, 2025. At this day-long immersive event, the scientists of LLO will share our research with you and deepen your understanding of Earth’s largest lakes. From quantifying microplastics to spearheading the field of winter limnology, the science being conducted at LLO underpins a new era of water stewardship. Come join us on this journey.

The event will kick off with a morning interpretive cruise followed by an afternoon of demonstrations, presentations, activities, and films. Lunch is included with purchase of a ticket. Tickets are on sale now through July 13th.
