Mcnutt Lake

Oneida County, WisconsinLimited DataMesotrophic

On the LakeGrade scale Mcnutt Lake grades a B, with clarity at 12.0 ft and phosphorus readings still being added placing it above the Wisconsin median. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI near 41 places Mcnutt Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 38 ft puts Mcnutt Lake in the middle of Wisconsin's depth distribution. Mcnutt Lake is small — 14 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Mcnutt Lake ranks 58 of 134 in Oneida County — solidly in the upper half of the local distribution.

Mcnutt Lake has no invasive species recorded in Wisconsin state databases as of 2024, though prevention practices still apply at all access points. The fishery is bass-led, with 2 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.
