Eden Lake

Eden Lake grades an F: water clarity, phosphorus, and chlorophyll-a all rate poorly, placing it among the most stressed lakes monitored in Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Hypereutrophic conditions mean the lake is operating at the upper end of the productivity scale, with all the bloom risk that implies. Eden Lake is unusually deep for Minnesota at 77 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. The lake's 278 acres and 2.5 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within the 55 graded lakes of Stearns County, Eden Lake sits at rank 55, near the bottom of the county list.

Eden Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The fishery includes walleye alongside the lake's other 16 documented species — a notable draw for Minnesota anglers. A documented public access point at Eden Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a long ice-out record — 45 observations on file, with a median ice-out around Apr 7. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
