Real-time Stream Flow Sensor Net in Google Earth

The US Geological Survey (USGS) has released yet another sensor net of data with excellent visualization in Google Earth. This time their WaterWatch program has released real-time streamflow data compared to historical streamflow for the day of the year for all the states in the US and Puerto Rico. There are hundreds of sensors in this data set which tracks short-term changes (over several hours) in rivers and streams. The colors represent real-time streamflow compared to percentiles of historical daily streamflow for the day of the year. There is a legend explaining the colors, and you can click on the placemarks for more details. You can zoom down to each placemark and see where they are located in the satellite photos of Google Earth. The USGS previously released a real-time Earthquakes sensor net.
