WaterWatch—Current Water Resources Conditions

WaterWatch is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis. WaterWatch provides streamgage-based maps that:

  • Show the location of more than 3,000 long-term USGS streamgages;
  • Use colors to represent streamflow conditions compared to historical streamflow;
  • Feature a point-and-click interface allowing users to retrieve graphs of stream stage (water elevation) and flow;
  • Highlight locations where extreme hydrologic events, such as floods and droughts, are occurring.
