USGS Stream Gaging Network in NC

Real-Time Streamflow Data

 Monitoring streamflow in North Carolina since 1895  Monitored and measured the benchmark floods including those of 1916, 1940, 1945, 1954, 1977, 1996, 1999, 2004  Floyd the “Granddaddy” for eastern North Carolina 9

 Basic piece of data collected at the streamgage is river stage or gage height  Stage data is available on the web at: nc.water.usgs.gov

Discharge or Streamflow is the second key component and must be measured by USGS staff directly or indirectly at stream gages

12  River stage data is routinely transmitted via satellite every 1 to 4 hours and displayed on the internet.  During extreme events data can be transmitted as frequently as every 15 minutes

 Streamflow or discharge data are critical to the flood forecasting needs of the National Weather Service  Ninety-eight percent of stations used for real-time river forecasting are operated by the U S Geological Survey  The streamflow data are used in models for flood forecasting Stream Gaging and Flood Forecasting A Partnership of the U.S. Geological Survey and the National Weather Service U.
