How Clean Is Becker Lake?
Becker Lake does not have enough monitoring data to grade. Its EPA monitoring record does not meet the evidence bar for a letter grade, so it is published unrated — that is an absence of evidence, not a poor result. The measurements below are what the record does contain. Phosphorus: 60 µg/L. Chlorophyll-a (algae): 43.5 µg/L. Trophic State Index: 65.
