Lower Red Lake: West Central
Beltrami County, MinnesotaMesotrophic
On the LakeGrade scale Lower Red Lake: West Central grades a B, with clarity at 13.1 ft and 34 µg/L of phosphorus placing it above the Minnesota median. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
Mesotrophic conditions dominate at Lower Red Lake: West Central: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. 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 86 graded lakes of Beltrami County, Lower Red Lake: West Central sits at rank 69, near the bottom of the county list.
Lower Red Lake: West Central has no invasive species recorded in Minnesota state databases as of 2025, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Lower Red Lake: West Central, 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.
