What is USGS WaterALERT?

The U.S. Geological Survey WaterAlert service sends e-mail or text messages when certain parameters measured by a USGS data-collection station exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported through the USGS Cooperative Water Program, the USGS National Streamflow Information Program, and by USGS data-collection partners, including numerous federal, state, and local agencies. All WaterAlert data are made available from the National Water Information System.

Real-time data from USGS gages are transmitted via satellite or other telemetry to USGS offices at various intervals; in most cases, once every 1 or 4 hours. Emergency transmissions, such as during floods, may be more frequent. Notifications will be based on the data received at these site-dependent intervals.
