Sorenson Lake

Sorenson Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Crow Wing County. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Trophically, Sorenson Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 46 ft puts Sorenson Lake in the middle of Minnesota's depth distribution. The lake is compact at 92 acres, with 1.7 miles of shoreline and little volume to buffer nutrient inputs. Sorenson Lake ranks 45 of 120 in Crow Wing County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Sorenson Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Sorenson Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Sorenson Lake — most use is by shoreline residents and their guests. The lake has a partial ice record — 18 observed ice-outs, centered near Apr 12. 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.
