The graphic above is a clickable map. Each river basin (outlined
in white) is a clickable region which takes you to a zoomed map of
the same area. The plotted points represents places where recent
river gage readings are available, and are colored according to their
values. The values are the latest data we have received and
are no older than 12 hours prior to the date/time stamp on the graphic.
Orange, magenta, and red dots represent river points that are
in flood. Yellow dots represent those which are under flood
stage, but are high enough to merit some internal action (e.g.,
perhaps a crest forecast is issued, or a forecast is issued more
frequently). Green dots represent stages that are below the
action stage and are not high enough to merit much hydrologic concern.
This map is automatically generated and may be posted to this
web site before quality control measures have been completed on
the data.
Some of the data is shown is provided by the U.S. Geological Survey,
the U.S. Army Corps. of Engineers, and other cooperative agencies.
