Data & Information

USGS WaterWatch--Current Water Resources Conditions

Map of real-time streamflow compared to historical streamflow for the day of the year (United States).

USGS Real-Time Water Data for the Nation

Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival.

USGS Historical Water Data for the Nation

These pages provide access to water-resources data collected at approximately 1.5 million sites in all 50 States, the District of Columbia, and Puerto Rico.

USGS Suspended Sediment

USGS Benchmark Glaciers

The USGS operates a long-term "benchmark" glacier program to monitor climate, glacier geometry, glacier mass balance, glacier motion, and stream runoff.

USGS Instantaneous Data Archive (IDA)

This web site has been established to make available as much historical instantaneous data from USGS data collection stations as possible. Although this site currently serves instantaneous discharge (streamflow) data only, work is planned to extend it to other time-series parameters in the future.
