Streamflow

Tamarisk is an invasive shrub or small tree that is found across the American West.
The best starting point for USGS streamflow data is the interactive National Water Information System (NWIS): Mapper website.
USGS real-time streamflow data are typically recorded at 15-minute intervals, stored onsite, and then transmitted to USGS offices every 1 hour, depending on the data relay technique used.
Real-time USGS streamflow data are PROVISIONAL, meaning that the data have not been reviewed or edited. These data may be subject to significant change and are not official until reviewed and approved by the USGS.
At some USGS stream-gage installations, NOAA’s National Weather Service (NWS) maintains a separate stage sensor that is serviced by NWS technicians.
Stream stage is an important concept when analyzing how much water is moving in a stream at any given moment. Stage is the water level above some arbitrary point in the river and is commonly measured in feet.
The spelling of “gage” is part of our very rich USGS history. We use it with pride!
