Eddy Lake

Eddy Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average. 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.

At a TSI of 59, Eddy Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. A maximum depth of 37 ft puts Eddy Lake in the middle of Minnesota's depth distribution. Eddy Lake is small — 24 acres alongside 0.9 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Within the 33 graded lakes of Carlton County, Eddy Lake sits at rank 27, near the bottom of the county list.

No invasive species are currently listed at Eddy Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Eddy Lake, one of 13 fish species on record for the lake. The lake lacks a documented public access point, so visitor use is limited. The lake has a partial ice record — 17 observed ice-outs, centered near Apr 4. 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.
