Hyland Lake

The LakeGrade rubric puts Hyland Lake at a C: clarity at 4.6 ft, 39 µg/L of phosphorus, and a TSI of 56 signal an intermediate trophic state. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. Hyland Lake is a shallow lake at 12 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. The lake is compact at 84 acres, with 2.3 miles of shoreline and little volume to buffer nutrient inputs. Hyland Lake ranks 30 of 95 in Hennepin County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Hyland Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 9 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
