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).
Hidden Gems of the Yahara Watershed
Our watershed is full of well-known, well-visited locations. But there are some you may have missed. Check out these gems, hidden in plain sight.
A watershed moment for our lakes
On May 18th, 2022, more than 300 leaders throughout the Greater Madison-Dane County region met at The Edgewater on the shores of Lake Mendota. The meeting celebrated what promises to be a new era of collaboration to benefit our local waters. With a collective call to “Renew the Blue,” a 19-member coalition of organizations introduced what some might describe as a stakeholder declaration to a sold-out audience.

Yahara CLEAN Compact, Charting A Path Forward
A shared vision for clean, safe, and accessible lakes
In August 2019, leaders from government, business, and nonprofit organizations came together with a shared vision.
