Secchi Disk Monitoring

Lake Wisconsin has been monitored by volunteers since 1993. Volunteers monitor water clarity with a black and white Secchi disk. Volunteers are the source of the majority of Wisconsin’s lake water quality data, and their dedication is greatly appreciated. Additional monitoring has been done through projects funded in part by DNR Lake Grants and Aquatic Invasive Species Grants. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed here.

Additional information can be found on the Citizen Lake Monitoring Network (CLMN) website.
