Department of the Interior Online Mapping Tool Now Available

Online Mapping Tool Traces U.S. Streams and Rivers

The Department of the Interior has released a new online mapping tool that allows users to trace any major U.S. stream to its source or down to its watershed.  The above map highlights all the major tributaries that feed into the Mississippi River (covering over one million square miles).  The second map shows the White River from Muncie, Indiana, traveling down to the Gulf of Mexico.

The National Atlas Streamer also allows users to learn more about the places streams pass through in brief or detailed reports.  Users first zoom in to activate the trace buttons on the map.  Double-click on the map and choose “trace downstream” or “trace upstream.”  This tool will allow researchers to learn more about the streams in their area.
