Rose Lake

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

A TSI value of 33 puts Rose Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake bottoms out at 24 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. 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. Rose Lake ranks 16 of 32 in Langlade County — solidly in the upper half of the local distribution.

Rose Lake has at least one documented invasive species (Banded Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. Walleye are documented at Rose Lake, one of 4 fish species on record for the lake. A documented public access point at Rose Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
