Hallie Lake
Chippewa County, WisconsinLimited DataEutrophic
Hallie Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Wisconsin average.
A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. At only 13 ft deep, Hallie Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. The lake is compact at 79 acres, with partial shoreline records and little volume to buffer nutrient inputs. Hallie Lake ranks 14 of 15 in Chippewa County — at the lower end of the locally monitored distribution.
Eurasian watermilfoil is established at Hallie Lake, which can dampen recreational access and pressure the native plant community. Bass fishing is part of the appeal: the species list runs to 4, anchored by largemouth and/or smallmouth bass. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
