How Clean Is Mason Lake?
Mason Lake does not have enough monitoring data to describe. It does not have enough recent summer sampling for a nutrient or algae figure. That means the measurements are missing, not that the water is poor. Everything the monitoring record does contain is below. Water clarity (Secchi depth): 3 ft. Phosphorus: 21 µg/L. Chlorophyll-a (algae): 16.9 µg/L. Trophic State Index: 56.

How does Mason Lake compare?
Mason Lake has too little recent summer sampling to compare, so it is not compared with the Minnesota state average. Multi-year monitoring data shows water quality is improving based on 3 years of records.
