Lower Red Lake : West

Beltrami County, MinnesotaMesotrophic

On the LakeGrade scale Lower Red Lake : West grades a B, with clarity at 13.1 ft and 37 µg/L of phosphorus placing it above the Minnesota median. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. 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 67 of 86 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.
