Surface Water Conditions in North Carolina

The U.S. Geological Survey (USGS) network of monitoring stations provides real-time water-stage data at 270 sites, with streamflow computed at 219 locations, and rainfall recorded at 135 stations. These sites continuously record data at 15-minute intervals (or less) and transmit the data via satellite or UHF radio to be incorporated into the USGS National Water Information System for public dissemination.
