Hazeltine Lake

On the LakeGrade rubric Hazeltine Lake fails the cutoffs — a TSI of 77 and persistent algal pressure put it in the bottom tier. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The hypereutrophic status — TSI 77 — reflects sustained heavy nutrient loading from the surrounding watershed and frequent algal pressure. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Hazeltine Lake ranks 31 of 40 in Carver County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Hazeltine Lake — the lake remains off the Minnesota infested-waters roster. 3 fish species are on record, with panfish making up the recreational core. The lake lacks a documented public access point, so visitor use is limited. 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.
