Notice:Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake, Volcano, LANDSAT and Water information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.

Constituents Measured or Computed Continuously in Oregon

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 Oregon. Click on a constituent for more detailed information, including a list of where it is measured or computed.

Constituent Name Units Criteria
Computed discharge cubic feet per second (cfs)
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)
