Farquar Lake

Farquar Lake earns an F: 115 µg/L of phosphorus and clarity at 1.7 ft signal heavy nutrient loading from the surrounding watershed. 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.

A TSI above 70 puts Farquar Lake in hypereutrophic territory: visible blooms are common, and clarity rarely climbs even in early summer. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Within the 48 graded lakes of Dakota County, Farquar Lake sits at rank 47, near the bottom of the county list.

No invasive species are currently listed at Farquar Lake — the lake remains off the Minnesota infested-waters roster. 5 fish species are on record, with panfish making up the recreational core. No formal public access is documented at Farquar Lake — most use is by shoreline residents and their guests. Multiple sampling years from Minnesota PCA volunteers and partner agencies back the grade, so the letter should hold steady absent a major watershed shift.
