NOTICE: July 21, 2012 13:27 USGS is deploying a new release of the USGS Water Data for the Nation web site. There are many servers that need to be updated, so the process may take a couple of days. During this time period you may see an inconsistent user interface, as some servers are updated while others are not. A subsequent email will be sent when the release is complete.

Real-time data are still available at http://waterdata.usgs.gov/nwis
