Little Bass Lake
Becker County, MinnesotaMesotrophic
Little Bass Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.
Mesotrophic conditions dominate at Little Bass Lake: 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. Among the 93 graded lakes in Becker County, Little Bass Lake sits at rank 45, above the county median.
Little Bass Lake 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 Little Bass Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Little Bass Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
