Edith Lake

On the LakeGrade scale Edith Lake grades a B, with clarity at 8.2 ft and 14 µg/L of phosphorus placing it above the Minnesota median. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Edith Lake reaches 43 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 81 acres, Edith Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Among the 83 graded lakes in Washington County, Edith Lake ranks 20 — in the top quartile locally.

No invasive species are currently listed at Edith Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Edith Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. The grade is supported by multiple sampling years from Minnesota PCA volunteers and partner agencies, giving the letter a reasonably stable foundation.
