Bueber Lake

Cass County, MinnesotaEutrophic

The LakeGrade rubric puts Bueber Lake at a C: clarity at 6.2 ft, 37 µg/L of phosphorus, and a TSI of 54 signal an intermediate trophic state. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

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 32 ft puts Bueber Lake in the middle of Minnesota's depth distribution. Bueber Lake covers 132 acres alongside 2.0 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Bueber Lake ranks 132 of 133 in Cass County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Bueber Lake — the lake remains off the Minnesota infested-waters roster. The fishery is bass-led, with 12 documented species across the lake's records. Public access is available — the lake is on the Minnesota PCA public-access list. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
