Idaho Real-Time Water Quality

Constituents Measured or Computed Continuously in Idaho

Continuous measurements of constituents (water-quality parameters) can be obtained by direct measurement using sensors, or by indirect computation using models.

Below is a list of constituents continuously measured or computed by the USGS in Idaho. Click on a constituent for more detailed information, including a list of where it is measured or computed.

Constituent Name Units Criteria
Acoustic Signal Strength Decibels (dB)
Antimony, water, filtered, micrograms per liter micrograms per liter (ug/l)
Arsenic, dissolved micrograms per liter as arsenic (ug/L)
Computed discharge cubic feet per second (cfs)
Dissolved oxygen milligrams per liter (mg/L)
Gage height feet (ft)
pH standard units (std units)
Sediment Corrected Backscatter Decibels (dB)
Specific conductance at 25 degrees Celsius microsiemens per centimeter (uS/cm)
Suspended sediment concentration, water, unfiltered, estimated by regression equation milligrams per liter (mg/L)
Turbidity, measured as NTU or FNU formazin nephelometric units (FNU)
Water temperature degrees Celsius (°C)
