Little Wabana Lake

On the LakeGrade rubric, Little Wabana Lake pulls an A: clarity at 23.8 ft and 7 µg/L of phosphorus put it in the top bracket for Minnesota. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. The lake's 57 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. Little Wabana Lake covers 116 acres alongside 1.9 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Little Wabana Lake ranks 1 of 141 in Itasca County, putting it in the upper tier of locally monitored lakes.

Little Wabana Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The fishery is bass-led, with 6 documented species across the lake's records. No formal public access is documented at Little Wabana Lake — most use is by shoreline residents and their guests. The lake has a partial ice record — 8 observed ice-outs, centered near Apr 23. 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.
