Ever since hydrographers left Embudo, the USGS has collected streamflow data using nationally consistent methods. These methods have allowed the USGS to collect data to the highest practical standards. All methods used to collect streamflow data are documented in USGS publications, such as the Techniques of Water-Resources Investigations series. Many USGS procedures form the basis for handbooks issued by the International Standards Organization.
