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. |
USGS Water Data for the Nation Help System
During cold
weather, ice effects on stage, ground water levels, precipitation and
water quality parameters at some stream-gaging stations and wells are
likely. Data values reported on these pages may be significantly higher
or lower than actual values. Adjustment of data for ice effects can
only be done after detailed analysis. Users are encouraged to contact
this office for more information on specific stream-gaging stations or
wells.
