In 2017, community partners diverted 14,000 pounds of phosphorus from our lakes. This represents 30% of the way to the Yahara CLEAN goal to cut phosphorus to our lakes in half.
According to Department of Natural Resources criteria for deep and shallow lakes, water clarity was “good” on all lakes in 2017, except “fair” on Lake Wingra. Phosphorus levels were generally “fair,” but “poor” on Lake Kegonsa.
In 2017, beaches were closed 4% of the time on Lake Mendota, 7% of the time on Lake Monona, 1% of the time on Lake Wingra, and 21% of the time on Lake Waubesa. The beach on Lake Kegonsa is not regularly monitored.

The State of the Lakes Annual Report is presented each year at the Save Our Lakes Community Breakfast. In it, we report out to the community on the state of water quality in our lakes and our collective progress towards our phosphorus reduction goal.
The report highlights information from many partners to share the most up-to-date science on water quality in our lakes. We feature local projects, including work in urban areas to protect stormwater quality and progress on farms to keep nutrients on the fields and out of our lakes.
In addition, we provide more information about Clean Lakes Alliance and our efforts to engage the community and advocate for the lakes. This report serves as a reference and a resource, highlighting community progress towards cleaner, healthier lakes for all.
