May 22, 2013 15:45 EDT: Notice:
The outage of the GOES-13 East satellite that occurred earlier today, which kept USGS Water Data current condition data from being updated, is largely over. Only a few dozen sites, mostly east of the Mississippi River, are still affected.
USGS Current Water Data for the Nation
Daily Streamflow Conditions
76th - 90th
25th - 75th
10th - 24th
The colored dots on this map depict streamflow conditions as a
percentile, which is computed from the period of record for the
current day of the year. Only stations with at least 30 years of
record are used.
The gray circles indicate other stations that were not ranked in
percentiles either because they have fewer than 30 years of record or
because they report parameters other than streamflow. Some stations,
for example, measure stage only.

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. Data
from current sites are relayed to USGS offices via satellite,
telephone, and/or radio telemetry and are available for viewing within minutes
