Wescott Lake
Oconto County, WisconsinLimited DataOligotrophic
Wescott Lake sits at the top of the Wisconsin DNR grading rubric with an A, a mark reached by the cleanest lakes in Wisconsin. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.
A TSI value of 22 puts Wescott Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. A maximum depth of 27 ft puts Wescott Lake in the middle of Wisconsin's depth distribution. The lake is compact at 40 acres, with partial shoreline records and little volume to buffer nutrient inputs. Wescott Lake sits at rank 38 of 66 in Oconto County, in the lower half of the local distribution.
Wescott Lake has at least one documented invasive species (Banded Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. The fishery is bass-led, with 3 documented species across the lake's records. 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.
