Stauffer Lake

On the LakeGrade rubric, Stauffer Lake pulls an A: clarity at 14.1 ft and 12 µg/L of phosphorus put it in the top bracket for Minnesota. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI value of 39 puts Stauffer Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. 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 Chisago County's 31 graded waters, Stauffer Lake sits at rank 1, near the top of the local distribution.

No invasive species are currently listed at Stauffer Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Stauffer Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
