Brooks Lake

The LakeGrade rubric puts Brooks Lake at a C: clarity at 5.6 ft, 32 µg/L of phosphorus, and a TSI of 53 signal an intermediate trophic state. 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. A maximum depth of 21 ft puts Brooks Lake in the middle of Minnesota's depth distribution. Brooks Lake covers 100 acres alongside 1.7 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 64 graded lakes in Wright County, Brooks Lake sits at rank 30, above the county median.

Brooks Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. Walleye are documented at Brooks Lake, one of 6 fish species on record for the lake. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
