Little Elbow Lake
Mahnomen County, MinnesotaMesotrophic
Little Elbow Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. 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.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake bottoms out at 18 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Little Elbow Lake covers 168 acres alongside 3.9 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Mahnomen County's 16 graded lakes, Little Elbow Lake ranks 9 — below the local median, though not at the bottom.
Little Elbow Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Little Elbow Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. 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.
