National Water Model(NWM) Stream Analysis Web Service <\/span> is built by processing the analysis assimilation output of the National Water Model river network based data. All output of the river network dataset have the same geospatial extent covering all of CONUS with partial coverage into Canada and Mexico. Currently, the service contains two layers: one depicting streamflow values and the other indicating streamflow anomalies.\n<\/p>\nEach layer contains 6 sub layers each with varying levels of simplification and filtering to make visualization more performant. There is also an additional labels layer which shows known stream names at the lowest scale. The streamflow layer colorizes streams according to the rate in which water is flowing through the stream while the anomaly layer colorizes streams according to how far their flow values deviate from normal flow values. All flow values are in cubic feet per second (CFS). Model Output Version: v3.0.\n<\/p>
