Sandy Lake

On the LakeGrade scale Sandy Lake grades a B, with clarity readings still being added and 21 µg/L of phosphorus placing it above the Minnesota median.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. 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. Among the 187 graded lakes in St. Louis County, Sandy Lake sits at rank 49, above the county median.

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