Lake of Dreams

Florence County, WisconsinLimited DataOligotrophic

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

Trophically, Lake of Dreams 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. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Lake of Dreams ranks 31 of 39 in Florence County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Lake of Dreams — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Lake of Dreams, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
