LakeForecast water quality monitoring in 2022

 In 2022, our volunteers embarked on the 10th season of LakeForecast water quality monitoring. This work involved collecting nearshore condition reports at piers, beaches, parks, and access points around the five Yahara lakes. From May through September, volunteers measured water clarity, recorded air and water temperature, identified the presence of green algae and cyanobacteria, and noted additional visual observations. Reports are entered into the LakeForecast app where all data are updated in real time.

Cyanobacteria on Lake Mendota at the Memorial Union

Cyanobacteria

All five Yahara lakes saw cyanobacteria (blue-green algae) blooms throughout the summer of 2019. One bloom in particular on Lake Mendota was quite large, covering at least an area from Picnic Point to the Memorial Union on August 1st. The bloom was well-documented by photos from community members as having a green pea soup-like consistency.

Cyanobacteria blooms are often bright green, but can also appear in shades of brown, blue, and white. Typically, blooms are spotted on warm days with calm winds. On August 1st, Madison reported a high of 81 degrees with an average wind speed of two miles per hour.

Flooded pier on Lake Mendota

Clean Lakes Alliance Statement to Dane County Lake Level Task Force

This statement was presented by Clean Lakes Alliance Executive Director James Tye to the Dane County Lake Level Task Force on March 5, 2019.

Clean Lakes Alliance applauds the leadership of the Dane County Board and the Dane County Executive in putting $12 million toward flood recovery and lake improvement projects in the 2019 budget, and in creating the Technical Work Group and task force to address recent flooding around the Yahara Chain of Lakes. We believe these initiatives help move us toward becoming a more resilient community. But we need to work together as a community to address the increasing volume of water and runoff BEFORE it enters our lakes and waterways.

Lake Mendota Ice

This is the start of something big

A message from Clean Lakes Alliance Executive Director, James Tye

Dear Friends,

As we close the books on a difficult year for our lakes, I want to take a moment to reflect on what went well, and what we can do to start 2019 off in the right direction.

Lake Monona and Downtown Madison

In Madison, Wisconsin, you can’t “say it all” until you’ve said Mendota, Monona, Wingra, Waubesa and Kegonsa. These five lakes are an integral part of our culture, and one of the major reasons Madison ranks as a “most livable” city year after year. Their waters entice us to visit, work or study here, and often to stay. When our lakes are healthy, our communities can flourish. That is the philosophy behind our work: Healthy Lakes. Healthy Communities.
