Master Man Lake

On the LakeGrade scale Master Man Lake grades a B, with clarity at 4.5 ft and 19 µg/L of phosphorus placing it above the Minnesota median. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.

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. Master Man Lake ranks 23 of 83 in Washington County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Master Man Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Master Man Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Master Man 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.
