Holland Lake

Holland Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Trophically, Holland Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's 55 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. Holland Lake is small — 38 acres alongside 1.3 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Holland Lake ranks 1 of 36 in Dakota County, putting it in the upper tier of locally monitored lakes.

Holland Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The fishery is bass-led, with 6 documented species across the lake's records. No formal public access is documented at Holland Lake — most use is by shoreline residents and their guests. Multiple sampling years from Minnesota PCA volunteers and partner agencies back the grade, so the letter should hold steady absent a major watershed shift.
