Lake Pesobic

Lake Pesobic sits at the top of the Wisconsin DNR grading rubric with an A, a mark reached by the cleanest lakes in Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

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. At 147 acres, Lake Pesobic fits the Wisconsin median for monitored lakes, with partial shoreline records. Lake Pesobic sits at rank 14 of 21 in Lincoln County, in the lower half of the local distribution.

An invasive species record — Chinese Mystery Snail — has been logged at Lake Pesobic; Wisconsin DNR maintains the official infested-waters list. The fishery includes walleye alongside the lake's other 4 documented species — a notable draw for Wisconsin anglers. A documented public access point at Lake Pesobic makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
