Lake Keesus
Lake Keesus was monitored by volunteers between 1987 and 2013. 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. Lake Keesus is also part of DNR's long term trend monitoring project. Additional monitoring has been done through projects funded in part by DNR Lake Grants. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
