Water quality measurements for Becker Lake
These are the measurements Minnesota PCA publishes for Becker Lake, shown as reported. The condition class beside each reading is the EPA National Lakes Assessment class for this lake’s ecoregion.
No clarity data. Phosphorus 60 µg/L. Chlorophyll-a 43.5 µg/L. TSI 65.
| Measure | Reading | Where it sits |
|---|---|---|
| Water clarity (Secchi depth) | No reading How deep a black-and-white disk stays visible from the surface. Higher is clearer. | |
| Total phosphorus | 60µg/L | Measured, not scored The nutrient that most limits algae growth in freshwater. More phosphorus, more algae potential. |
| Chlorophyll-a (algae) | 43.5µg/L | Measured, not scored The green pigment in algae — a direct measure of how much algae is in the water. |

Minnesota DNR's Targeted Survey on August 9, 2023 caught 1.24 walleye per hour of electrofishing at Becker Lake. Length samples in the latest survey that recorded them ran 6–7 inches.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Becker Lake’s water-quality measurements separately, and the water-quality trend over 2 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

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…
