Upper Post Lake
Langlade, Oneida County, 765 Acres


Upper Post Lake was monitored by volunteers between 1986 and 2018. 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. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
