GIS data for the Advanced Hydrologic Prediction Service. “This page links to “Shapefiles” and “KMZ” files (generated every 15 minutes) which are compressed “KML” files compatible with several GIS software applications…The majority of the observed water level data displayed on the AHPS web pages originates from the United States Geological Survey’s (USGS) National Streamflow Information Program which maintains a national network of streamgages. In addition, real-time water level information is collected from other federal, state, and local streamgage networks.” – National Weather Service
