Ozawindib Lake

On the LakeGrade rubric, Ozawindib Lake pulls an A: clarity at 19.0 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.

Trophically, Ozawindib Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. Ozawindib Lake is unusually deep for Minnesota at 80 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. At 159 acres, Ozawindib Lake fits the Minnesota median for monitored lakes, with 4.1 miles of shoreline. Within Clearwater County's 40 graded waters, Ozawindib Lake sits at rank 10, near the top of the local distribution.

No invasive species are currently listed at Ozawindib 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. Ice-out has been recorded 14 times at Ozawindib Lake, with a median around Apr 20. 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.
