How Clean Is Alder Lake?
Alder 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): 13.8 ft. Phosphorus: 8 µg/L. Chlorophyll-a (algae): 3.1 µg/L. Trophic State Index: 38.

How does Alder Lake compare?
Alder 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 stable based on 2 years of records.
