[OSGeo-Discuss] Open "StreamMap"?

The USGS has a KML map of their stream gauges and water quality sensors in
the US. Here's a good starting point: http://water.usgs.gov/wateralert/
Getting an embeddable realtime view can be more difficult - I have a
regional example here
http://www.ce.cmu.edu/~wquest/Dunkard%20Images/SensorMap.html
Having worked on a water data research project, there are several standards
and data models being discussed and used by researchers. The USGS has
shapefiles and IDs of water catchment areas for each major stream - that'll
save you a great deal of trouble with DEM terrain data. You don't tend to
see these files or stream data online, because the science is mostly done
with desktop GIS and rarely publicized. I believe that the NSF, EPA, and
local governments were backing http://his.cuahsi.org/ and
http://water.epa.gov/scitech/datait/models/basins/index.cfm for sharing
information on streams. It would be good to have tie-ins to these
successful programs.
