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 and phosphorus 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.
