Beaver Lake

On the LakeGrade scale Beaver Lake grades a B, with clarity at 6.5 ft and 17 µg/L of phosphorus placing it above the Wisconsin median. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

Mesotrophic conditions dominate at Beaver Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake bottoms out at 20 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. The lake is compact at 62 acres, with partial shoreline records and little volume to buffer nutrient inputs. Beaver Lake sits at rank 133 of 191 in Vilas County, in the lower half of the local distribution.

Beaver Lake has no invasive species recorded in Wisconsin state databases as of 2026, though prevention practices still apply at all access points. The fishery includes walleye alongside the lake's other 5 documented species — a notable draw for Wisconsin anglers. 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.
