Kramer Lake

On the scoring rubric Kramer Lake grades a D: clarity at 1.0 ft and 359 µg/L of phosphorus keep it in the lower bracket for Washington County. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

The hypereutrophic status — TSI 70 — reflects sustained heavy nutrient loading from the surrounding watershed and frequent algal pressure. 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 Washington County's 83 graded lakes, Kramer Lake ranks 61 — below the local median, though not at the bottom.

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