Gunn Lake

Gunn Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Itasca County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Trophically, Gunn Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. 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. Among the 141 graded lakes in Itasca County, Gunn Lake sits at rank 51, above the county median.

No invasive species are currently listed at Gunn Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Gunn Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Gunn 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.
