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.

In the Yahara Watershed, salt applied to roads and sidewalks ultimately makes its way into our lakes and our drinking water. Road salt has been used as a deicer on streets in Dane County since the 1950s, and over the last 50 years, average concentrations of chlorides from salt in our lakes have steadily increased.
