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) |
