Mendota Freeze Contest

media release: Winter’s arrival was briefly marked by Lake Mendota freezing on December 25, 2024, as determined by the Wisconsin State Climatology Office late on January 2, 2025. Dense fog during this time led to some deliberation within the office about whether the ice lasted the required 24 hours. Furthermore, fluctuating temperatures have since caused any remaining ice to thaw, leaving residents to navigate the unpredictable nature of this year’s winter. Clean Lakes Alliance also reminds community members to exercise caution around the lake, as ice conditions remain inconsistent despite the official freeze date.

Dan Standiford, this year’s Mendota Freeze Contest winner, expressed his disbelief at the early freeze date. “I still can’t believe it!” Standiford shared, “I’ve been doing this contest for probably 15 years, ever since it’s been going on, and never even come close.”

James Tye, executive director of Clean Lakes Alliance, reflected on the complexity of determining the freeze date. “The freezing of Lake Mendota is always a fascinating milestone for our community, but this year’s process highlights the nuances of weather patterns and environmental conditions. This is a powerful reminder of how climate change is adding layers of unpredictability to what used to be straightforward seasonal events.”

The freezing of Greater Madison’s largest lake typically signals not only the heart of the season but also the countdown to Clean Lakes Alliance’s annual Frozen Assets Festival, taking place from February 3-9, 2025. This year’s event promises to continue a unique celebration of winter, community, and lake stewardship, regardless of ice conditions.

Frozen Assets Festival highlights include the World Snow and Ice Sailing Championships and the ever-popular Frozen Assets 5K Run/Walk on Saturday, February 8th. Additional family-friendly activities, like ice skating and hot chocolate, make this a must-attend event for all ages. Why It Matters: The Festival highlights Clean Lakes Alliance’s year-round efforts to spread awareness about water quality issues in the Yahara Watershed.
