There are a good number of gages that are currently on the AFWS web site that are not available in this map layer at this time, such as the stream flow gage on the Rocky Broad River in North Carolina.

If a reach is linked to an online gage, it's put-in location is color coded by whether or not it is currently running - in just the same way that the reaches are color coded on each state summary page. text/html 2007-06-30T16:36:47-05:00 /content/Wiki/rivers:kml:getips?rev=1183235807&do=diff .

Unfortunately, this website can be rather difficult to navigate. But using this map layer will provide easier and geographically-oriented access to this website's gold mine of hydrologic data. text/html 2008-03-30T18:04:20-05:00 /content/Wiki/rivers:kml:nwsradarimages?rev=1206914660&do=diff .

[:rivers:kml:ge_icon.jpg] Google Earth (GE) now supports, to some degree, web map services (WMS), which enables you to add map layers from a wide variety of third-party map servers. Here’s how it works. When you zoom to a particular geographic area in GE, it makes a request to the third-party server for a map of that region. The server then renders a map image, like a jpeg image from your digital camera, and sends it back to the GE software on your computer. The down side of having access to…
