Gilmore Lake

Gilmore Lake 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.

Trophically, Gilmore Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 24 ft puts Gilmore Lake in the middle of Wisconsin's depth distribution. At 314 acres, Gilmore Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Gilmore Lake ranks 49 of 140 in Oneida County — solidly in the upper half of the local distribution.

An invasive species record — Chinese Mystery Snail — has been logged at Gilmore Lake; Wisconsin DNR maintains the official infested-waters list. Walleye are documented at Gilmore Lake, one of 5 fish species on record for the lake. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
