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.
