Whiskey Lake

On the LakeGrade rubric, Whiskey Lake pulls an A: clarity at 18.8 ft and phosphorus readings still being added put it in the top bracket for Minnesota.

A TSI value of 35 puts Whiskey Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake bottoms out at 46 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Whiskey Lake covers 160 acres alongside 2.4 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Whiskey Lake ranks 7 of 51 in Douglas County, putting it in the upper tier of locally monitored lakes.

Zebra mussel presence at Whiskey Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. The fishery includes walleye among the lake's 13 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
