Corabelle Lake

Corabelle Lake grades an F: water clarity, phosphorus, and chlorophyll-a all rate poorly, placing it among the most stressed lakes monitored in Minnesota. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The hypereutrophic status — TSI 84 — reflects sustained heavy nutrient loading from the surrounding watershed and frequent algal pressure. A maximum depth of just 6 ft means sediment-bound phosphorus releases back into the water column whenever wind stirs the bottom — a classic shallow-lake dynamic. Corabelle Lake covers 106 acres alongside 1.5 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Corabelle Lake ranks 9 of 10 in Murray County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Corabelle Lake — the lake remains off the Minnesota infested-waters roster. 8 fish species are on record, with panfish making up the recreational core. A documented public access point at Corabelle Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
