Friedrich Pond

The LakeGrade rubric puts Friedrich Pond at a C: clarity at 2.3 ft, 61 µg/L of phosphorus, and a TSI of 58 signal an intermediate trophic state. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.

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. Friedrich Pond sits at rank 46 of 83 in Washington County, in the lower half of the local distribution.

Friedrich Pond has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Friedrich Pond, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Friedrich Pond — 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.
