Rest Lake

Vilas County, WisconsinLimited DataMesotrophic

Rest Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Mesotrophic conditions dominate at Rest Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake's 53 ft maximum depth is in the upper tier for Wisconsin — deep enough for cold-water fish to find refuge in summer. Rest Lake covers 655 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Rest Lake sits at rank 115 of 191 in Vilas County, in the lower half of the local distribution.

An invasive species record — Banded Mystery Snail — has been logged at Rest Lake; Wisconsin DNR maintains the official infested-waters list. Walleye are documented at Rest Lake, one of 6 fish species on record for the lake. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
