Real-time data from USGS monitoring locations are transmitted via satellite or other telemetry to USGS offices at various intervals; in most cases, once every hour. Emergency transmissions, such as during floods, may be more frequent. Notifications will be based on the data received at these site-dependent intervals.
Read our Check Status User blog post to get an idea of common use cases for WaterAlert.
The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.
