Why Becker Lake has no grade
We grade a lake only when its monitoring record clears the evidence bar: at least three phosphorus or chlorophyll-a samples in the last ten years, scored against EPA National Lakes Assessment thresholds for this lake’s ecoregion. For Becker Lake, no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Sampling here has recorded phosphorus and algae (chlorophyll-a), but not water clarity.
Not Rated is not an F. It is EPA Integrated Reporting Category 3 — insufficient information. The water here may be excellent or poor; nobody has measured enough of it to say. Everything below that has been measured is still reported on this page.
Sampling is run by MPCA and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.

From the 2025-09-23 survey
On September 23, 2025, DNR Fisheries used night electrofishing to sample young-of-year Walleyes in White Earth Lake. This sampling has been done annually for the past 15 years and is used to help determine the success of natural reproduction within White Earth Lake. During the 2025 assessment, 18 young-of-year…
