Wolf Lake

Wolf Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. Secchi readings are the weakest of the scored parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

A TSI near 46 places Wolf Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. At 57 ft of maximum depth, Wolf Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. Wolf Lake covers 1,076 acres alongside 8.0 miles of shoreline, large enough that conditions can vary meaningfully between bays. Wolf Lake sits at rank 53 of 92 in Beltrami County, in the lower half of the local distribution.

Wolf Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Wolf Lake's fishery is anchored by muskellunge, with 18 documented species in total — a destination water for muskie anglers. Public access is available — the lake is on the Minnesota PCA public-access list. Ice-out has been recorded 9 times at Wolf Lake, with a median around Apr 25. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
