Rose Lake

On the LakeGrade rubric, Rose Lake pulls an A: clarity readings still being added and 18 µg/L of phosphorus put it in the top bracket for Minnesota.

Mesotrophic conditions dominate at Rose Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 31 ft puts Rose Lake in the middle of Minnesota's depth distribution. Rose Lake is small — 59 acres alongside 1.3 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Rose Lake ranks 11 of 187 in St. Louis County, putting it in the upper tier of locally monitored lakes.

Rose 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 Rose Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Rose Lake — most use is by shoreline residents and their guests. 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.
