Lac Lavon Lake

On the LakeGrade scale Lac Lavon Lake grades a B, with clarity at 12.8 ft and phosphorus readings still being added placing it above the Minnesota median. 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 32 ft puts Lac Lavon Lake in the middle of Minnesota's depth distribution. The lake is compact at 66 acres, with 2.1 miles of shoreline and little volume to buffer nutrient inputs. Among the 36 graded lakes in Dakota County, Lac Lavon Lake ranks 4 — in the top quartile locally.

Eurasian watermilfoil has been documented at Lac Lavon Lake, requiring shoreline management to keep dense mats from crowding native vegetation. Bass fishing is part of the appeal: the species list runs to 9, anchored by largemouth and/or smallmouth bass. A documented public access point at Lac Lavon Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 9 observed ice-outs, centered near Apr 10. 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.
