Lake Nokomis

On the LakeGrade scale Lake Nokomis grades a B, with clarity at 11.8 ft and 36 µg/L of phosphorus placing it above the Wisconsin median. 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 near 49 places Lake Nokomis in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 33 ft puts Lake Nokomis in the middle of Wisconsin's depth distribution. At 2,274 acres, Lake Nokomis is one of the larger lakes in Oneida County, with partial shoreline records supporting multiple distinct use patterns. Within the 140 graded lakes of Oneida County, Lake Nokomis sits at rank 121, near the bottom of the county list.

Eurasian watermilfoil is established at Lake Nokomis, which can dampen recreational access and pressure the native plant community. The fishery includes walleye alongside the lake's other 6 documented species — a notable draw for Wisconsin anglers. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
