It’s Water Quality and Availability Month at the USGS!
Explore the USGS Water Data for the Nation and other USGS water resources below that are critical for monitoring, assessing, and characterizing the health and availability of our nation’s water assets. “WaterAlert” is real-time data from USGS monitoring locations that are transmitted, in most cases, once every hour. Emergency transmissions, such as during floods, may be more frequent. Get notifications for changes in water conditions based on thresholds you choose. USGS science supports national priorities and local communities from coast-to-coast.
