Constituents Measured or Computed Continuously in Colorado
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 Colorado. 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) | |
Dissolved solids | milligrams per liter (mg/L) | |
Load dissolved solids | tons per day (tons/day) | |
pH | standard units (std units) | |
Selenium, water, filtered, micrograms per liter | micrograms per liter (ug/l) | |
Specific conductance at 25 degrees Celsius | microsiemens per centimeter (uS/cm) | |
Water temperature | degrees Celsius (°C) |
