Franklin Lake

Franklin Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Oneida County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Trophically, Franklin Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. At 159 acres, Franklin Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Franklin Lake ranks 25 of 140 in Oneida County, putting it in the upper tier of locally monitored lakes.

No invasive species are currently listed at Franklin Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 5 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
