We had so much fun throughout the nine days of Frozen Assets 2023 and we hope you did too! More than 8,000 lake enthusiasts from near and far joined us for science demonstrations, musical performances, ice skating, food and drinks, ice sculpture carving, a chance to try new winter activities, face painting, networking, a chance to run or walk in the only 5K on a frozen lake in North America, and more! We THANK YOU for supporting lakes Mendota, Monona, Wingra, Waubesa, and Kegonsa!
Join Clean Lakes Alliance on Saturday, February 4th from 10 a.m. to 3 p.m. for Frozen Assets! The family-friendly festival on frozen Lake Mendota and at The Edgewater helps connect the community with the lake through free winter activities.
Festival attendees can see skydiving, figure skating, dance, speed skating, science, and large show kite demonstrations. Festival goers can also try pond hockey, snowshoeing, and skating; meet Bucky Badger, see the Mary B. Iceboat up close, and more!
The day will start with the annual Frozen Assets 5K Run/Walk on frozen Lake Mendota. Starting and finishing at The Edgewater, the run/walk is the only 5K in North America held entirely on a frozen lake. Registration includes a soft t-shirt compliments of Lands’ End and a post-race beer/seltzer (21+) compliments of Michelob Ultra. Kids 10 and under can participate for free with a registered adult.
Each year, this FUNraiser, FRIENDraiser, and FUNDraiser highlights the year-round value of our lakes, while raising money to protect our waters through lake improvement projects, educational programming, and our volunteer water quality monitoring program.
When the lakes freeze in Greater Madison, they become our largest parks. Clean Lakes Alliance hopes community members and visiting guests can interact with our “frozen assets” and appreciate their importance, even in the middle of the winter.

Frigid air temperatures, combined with cold water and low winds, helped Lake Mendota officially freeze on December 25th, 2022. The declaration came from the Wisconsin State Climatology Office. Lake Mendota, the largest lake in the Yahara Watershed, froze five days after December 20th. December 20th is the median ice-on date for the largest lake in the Yahara River Watershed. The Christmas Day freeze date is over a month shy of January 30th – which is the latest date that ice-on has ever been declared (1/30/1932).

Get ready for a full slate of activities on ice and on land at the 2020 Frozen Assets Festival! Clean Lakes Alliance’s sixth annual winter festival is expanding to a full week of fun at The Edgewater in Madison, Wisconsin from Sunday, February 2nd through Saturday, February 8th.
Warm December and early January temperatures caused a delay in Lake Mendota’s ice-on date. However, the recent cold air temperatures combined with light winds and cold water helped Lake Mendota officially freeze on Sunday, January 12th, 2020, as declared by the Wisconsin State Climatology Office.
Take a break from the hilly pavement and bring your stride to the ice. In this 5K race, participants will run, walk, or snowshoe across the ice on iconic Lake Mendota with beautiful views of downtown Madison. The course will start and end at The Edgewater, right in the heart of the Frozen Assets Festival!
The sixth annual Frozen Assets Festival will take place on Saturday, February 8th at The Edgewater. As always, this family-friendly daytime event will be FREE and open to all. Learn more at cleanlakesalliance.org/frozen-assets.
Race organizers reserve the right to alter the course due to factors including, but not limited to, ice conditions and weather. If conditions are deemed unsafe, the event may be cancelled or moved to an alternate location. Participants will be notified of any changes ahead of the event.

Despite warm weather in Madison over the weekend, cool nights, light winds, and cold water helped Lake Mendota officially freeze on Saturday, December 15th. Lake Mendota, the largest lake in the Yahara Watershed, froze eight days after the smallest lake in the watershed, Lake Wingra, which officially froze on December 7th. Lake Monona officially froze on December 11th.
The Wisconsin State Climatology Office requires ice to hold for a period of 24 hours before a lake can officially be declared frozen over. After ice took shape this weekend, staff waited to see whether it would hold out through the warm daytime temperatures. The December 15th freeze date is 12 days ahead of last year’s December 27th freeze date, and a surprising five days ahead of the December 20th median freeze date. The latest freeze date for Lake Mendota was January 30th – which happened in the winter of 1932.
The Wisconsin State Climatology Office makes the official determination as to whether the lake is frozen. The climatologists use the same guidelines they have used for decades to determine whether the lakes are iced over. This allows for a continuity in data collection.
