How Clean Is Friends Lake?
Friends 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. Water clarity (Secchi depth): 16.3 ft. Trophic State Index: 37.
