Fedji Lake

Fedji Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

At a TSI of 60, Fedji Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. A maximum depth of just 6 ft means sediment-bound phosphorus releases back into the water column whenever wind stirs the bottom — a classic shallow-lake dynamic. Fedji Lake covers 172 acres alongside 2.6 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Fedji Lake ranks 2 of 5 in Watonwan County — solidly in the upper half of the local distribution.

Fedji Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Fedji Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Fedji Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
