SYSTEM NOTICE: Friday, February 10, 2012, through Sunday February 12, 2012 there will be a planned power outage in one of our USGS facilities. This should not affect the availability of any data that we serve; however, the mapping interface which displays sites on a map will be unavailable. A follow-up notice will be sent when the power is fully restored. All real-time current data will continue to be available at http://waterdata.usgs.gov/nwis.
