Phoebe Lake

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

Mesotrophic conditions dominate at Phoebe Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 25 ft puts Phoebe Lake in the middle of Minnesota's depth distribution. The lake's 610 acres and 15.1 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Cook County's 128 graded lakes, Phoebe Lake ranks 83 — below the local median, though not at the bottom.

Phoebe Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. Walleye are documented at Phoebe Lake, one of 7 fish species on record for the lake. No formal public access is documented at Phoebe Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
