Bittersweet Lake

Bittersweet Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Vilas County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Trophically, Bittersweet Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake bottoms out at 31 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 104 acres, Bittersweet Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Bittersweet Lake sits at rank 144 of 202 in Vilas County, in the lower half of the local distribution.

No invasive species are currently listed at Bittersweet Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 3 documented species across the lake's records. A documented public access point at Bittersweet Lake 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.
