Unnamed Lake

Unnamed 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. A maximum depth of 43 ft puts Unnamed Lake in the middle of Minnesota's depth distribution. Unnamed Lake is small — 36 acres alongside 1.1 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Among the 24 graded lakes in Sherburne County, Unnamed Lake sits at rank 7, above the county median.

Unnamed Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. Bass fishing is part of the appeal: the species list runs to 7, anchored by largemouth and/or smallmouth bass. No formal public access is documented at Unnamed Lake — most use is by shoreline residents and their guests. Ice-out has been recorded 11 times at Unnamed Lake, with a median around Apr 9. Multiple sampling years from Minnesota PCA volunteers and partner agencies back the grade, so the letter should hold steady absent a major watershed shift.
