How Clean Is Split Hand Lake?
Split Hand 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): 6 ft. Phosphorus: 21 µg/L. Chlorophyll-a (algae): 7.1 µg/L. Trophic State Index: 50.
