Lower Red Lake : West
Beltrami County, MinnesotaEutrophic
The LakeGrade rubric puts Lower Red Lake : West at a C: clarity at 4.0 ft, 37 µg/L of phosphorus, and a TSI of 57 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.
A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. 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. Lower Red Lake : West ranks 83 of 92 in Beltrami County — at the lower end of the locally monitored distribution.
No invasive species are currently listed at Lower Red Lake : West — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Lower Red Lake : West, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
