Lower Rice Lake

Clearwater County, MinnesotaLimited DataEutrophic

Lower Rice Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

At a TSI of 57, Lower Rice 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. Within the 40 graded lakes of Clearwater County, Lower Rice Lake sits at rank 38, near the bottom of the county list.

No invasive species are currently listed at Lower Rice Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Lower Rice Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
