Mildred Lake

Mildred Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Oneida County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI value of 28 puts Mildred Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. A maximum depth of 45 ft puts Mildred Lake in the middle of Wisconsin's depth distribution. At 168 acres, Mildred Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Among the 140 graded lakes in Oneida County, Mildred Lake sits at rank 46, above the county median.

Mildred Lake has at least one documented invasive species (Chinese Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. Walleye are documented at Mildred Lake, one of 4 fish species on record for the lake. A documented public access point at Mildred Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
