North Silver Lake

North Silver Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. At 200 acres, North Silver Lake fits the Minnesota median for monitored lakes, with partial shoreline records. North Silver Lake ranks 1 of 14 in Martin County, putting it in the upper tier of locally monitored lakes.

North Silver Lake has no invasive species recorded in Minnesota state databases as of 2025, though prevention practices still apply at all access points. The state fisheries records do not list documented species for North Silver Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at North Silver Lake — most use is by shoreline residents and their guests. Ice-out has been recorded 19 times at North Silver Lake, with a median around Mar 23. Multiple sampling years from Minnesota PCA volunteers and partner agencies back the grade, so the letter should hold steady absent a major watershed shift.
