Hubert Lake

Hubert Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Trophically, Hubert Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's 83 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. Hubert Lake covers 1,301 acres alongside 6.0 miles of shoreline, large enough that conditions can vary meaningfully between bays. Among the 120 graded lakes in Crow Wing County, Hubert Lake sits at rank 44, above the county median.

Zebra mussels have been documented at Hubert Lake, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. The fishery includes walleye alongside the lake's other 16 documented species — a notable draw for Minnesota anglers. A documented public access point at Hubert Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been logged at Hubert Lake more than two dozen times, putting the median around Apr 22 — a useful baseline for tracking climate trends. 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.
