Strandness Lake

Strandness Lake earns a D — measurements through 2024 show persistent nutrient pressure that limits clarity through the summer. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. At only 5 ft deep, Strandness Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. At 92 acres, Strandness Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Within the 25 graded lakes of Pope County, Strandness Lake sits at rank 21, near the bottom of the county list.

No invasive species are currently listed at Strandness 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. No formal public access is documented at Strandness Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
