NWIS Current Water Data (Real-Time Data)

June 22, 2021

The USGS provides Current Water Data for the Nation in real-time or near-real-time conditions at sites across the US. Current data typically are recorded at 15- to 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.
