Earley Lake

Earley Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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 in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. 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 Dakota County's 48 graded lakes, Earley Lake ranks 25 — below the local median, though not at the bottom.

Eurasian watermilfoil is established at Earley Lake, which can dampen recreational access and pressure the native plant community. The state fisheries records do not list documented species for Earley Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Earley 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.
