Webb Lake

Burnett County, WisconsinLimited DataMesotrophic

The LakeGrade rubric puts Webb Lake at a C: clarity at 8.0 ft, phosphorus readings still being added, and a TSI of 47 signal an intermediate trophic state. 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.

The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's 759 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. Webb Lake sits at rank 40 of 57 in Burnett County, in the lower half of the local distribution.

No invasive species are currently listed at Webb Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Webb Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
