Round Lake

Round Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. A maximum depth of 27 ft puts Round Lake in the middle of Wisconsin's depth distribution. The lake's 208 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within the 57 graded lakes of Burnett County, Round Lake sits at rank 45, near the bottom of the county list.

Eurasian watermilfoil is established at Round Lake, which can dampen recreational access and pressure the native plant community. Walleye are documented at Round Lake, one of 5 fish species on record for the lake. 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.
