Round Lake

The LakeGrade rubric puts Round Lake at a C: clarity at 7.5 ft, phosphorus readings still being added, and a TSI of 48 signal an intermediate trophic state.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. A maximum depth of 16 ft puts Round Lake in the middle of Minnesota's depth distribution. Round Lake covers 101 acres alongside 1.6 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Itasca County's 141 graded lakes, Round Lake ranks 102 — below the local median, though not at the bottom.

No invasive species are currently listed at Round Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Round Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Round Lake — most use is by shoreline residents and their guests. The lake has a partial ice record — 11 observed ice-outs, centered near Apr 15. 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.
