Annabelle Lake

Annabelle Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

Mesotrophic conditions dominate at Annabelle Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Annabelle Lake reaches 30 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 194 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Vilas County's 191 graded lakes, Annabelle Lake ranks 97 — below the local median, though not at the bottom.

An invasive species record — Purple Loosestrife — has been logged at Annabelle Lake; Wisconsin DNR maintains the official infested-waters list. Walleye are documented at Annabelle Lake, one of 5 fish species on record for the lake. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
