Rose Lake

Langlade County, WisconsinLimited DataOligotrophic

Rose Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Langlade County. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Trophically, Rose 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. Rose Lake covers 115 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 32 graded lakes in Langlade County, Rose Lake ranks 6 — in the top quartile locally.

An invasive species record — Banded Mystery Snail — has been logged at Rose Lake; 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 Rose 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.
