2000 Moosup River
Monitored by: Al Ball, Lawson Cary
Algae Concentration as Measured by Chlorophyll Levels
Oligotrophic < 2.6 ppb, low algae levels
Mesotrophic 2.6-7.2 ppb, moderate algae levels
Eutrophic > 7.2 ppb, elevated algae levels; indicates an algae bloom
Hypereutrophic > 35 ppb, extremely high algae levels; "pea soup" conditions
Refer to URI Watershed Watch's Fact Sheet Algae in Aquatic Ecosystems for more information.
Dissolved Oxygen > 5 mg/L, good
Dissolved Oxygen 3-5 mg/L, low oxygen
Dissolved Oxygen < 3 mg/L, incapable of supporting aquatic life
Refer to URI Watershed Watch's Fact Sheet Dissolved Oxygen and Temperature for more information.
