Eagle Lake

Eagle Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake bottoms out at 35 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Eagle Lake covers 389 acres alongside 5.3 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Eagle Lake sits at rank 18 of 33 in Carlton County, in the lower half of the local distribution.

Eagle Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. Walleye are documented at Eagle Lake, one of 12 fish species on record for the lake. A documented public access point at Eagle Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 18 times at Eagle Lake, with a median around Apr 17. 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.
