Updated Sep 29

Escherichia coli (E. coli) Bacteria38.0 MPN/100mL

Common fecal coliform bacteria indicating possible sewage contamination. EPA recreational limit: <126 MPN/100mL.

Water Temperature10.6 °C

Water temperature directly affects fish metabolism and activity. Optimal range varies by species.

Nh3 (mg/L) (Water Quality Parameter)0.3

Nh3 (mg/L) - a water quality measurement. Contact local authorities for specific safety guidelines.

No3 (mg/L) (Water Quality Parameter)0.0

No3 (mg/L) - a water quality measurement. Contact local authorities for specific safety guidelines.

Turbidity (Water Clarity)0.8 NTU

Measures water cloudiness caused by suspended particles. Lower values indicate clearer water. <25 NTU is good.

Water Temperature10.6 °C

Water temperature directly affects fish metabolism and activity. Optimal range varies by species.

Electrical Conductivity199.6 µS/cm

Measures dissolved ions and minerals in water. Indicates salinity and pollution levels. Freshwater: 100-500 µS/cm.
