Wild Rice Lake Deep
Vilas County, WisconsinLimited DataMesotrophic
Wild Rice Lake Deep earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. 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. Wild Rice Lake Deep reaches 26 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Wild Rice Lake Deep covers 384 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within the 191 graded lakes of Vilas County, Wild Rice Lake Deep sits at rank 149, near the bottom of the county list.
Wild Rice Lake Deep has at least one documented invasive species (Banded Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. Walleye are documented at Wild Rice Lake Deep, one of 6 fish species on record for the lake. A documented public access point at Wild Rice Lake Deep makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
