Greeley Lake

On the LakeGrade scale Greeley Lake grades a B, with clarity at 9.0 ft and phosphorus readings still being added placing it above the Minnesota median. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake bottoms out at 43 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 23 acres, Greeley Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Within Itasca County's 141 graded lakes, Greeley Lake ranks 88 — below the local median, though not at the bottom.

Greeley Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. 1 fish species are documented at Greeley Lake, a mixed warm-water community typical for Minnesota lakes of this size. A documented public access point at Greeley Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
