Westwood Lake

Hennepin County, MinnesotaEutrophic

Westwood Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

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. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Among the 95 graded lakes in Hennepin County, Westwood Lake ranks 21 — in the top quartile locally.

No invasive species are currently listed at Westwood Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Westwood 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. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
