Unnamed Lake

On the LakeGrade rubric Unnamed Lake fails the cutoffs — a TSI of 78 and persistent algal pressure put it in the bottom tier. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI above 70 puts Unnamed Lake in hypereutrophic territory: visible blooms are common, and clarity rarely climbs even in early summer. 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. Unnamed Lake ranks 43 of 49 in Ramsey County — at the lower end of the locally monitored distribution.

Eurasian watermilfoil has been documented at Unnamed Lake, requiring shoreline management to keep dense mats from crowding native vegetation. The state fisheries records do not list documented species for Unnamed Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. Ice-out has been recorded 6 times at Unnamed Lake, with a median around Mar 31. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
