Lake Wingra

About Lake Wingra

Lake Wingra is a small, shallow lake located in the City of Madison. Because of its urban environment, the lake faces many challenges, including excess nutrients and road salt from urban runoff. The Lake Wingra watershed management plan, adopted by partners in 2015, seeks to address these and other watershed issues.
