Rice Marsh Lake

The LakeGrade rubric puts Rice Marsh Lake at a C: clarity at 7.7 ft, 34 µg/L of phosphorus, and a TSI of 51 signal an intermediate trophic state. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.

At a TSI of 51, Rice Marsh Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. 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 95 graded lakes in Hennepin County, Rice Marsh Lake ranks 14 — in the top quartile locally.

Rice Marsh Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Rice Marsh Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Rice Marsh 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.
