With the "Streams and waterbodies" shapefile from national atlas and this
dbfawk file, you'll get all the lakes, reserviors and bays in the country
a nice shade of cyan.

I only played with the "hydrogp020" shapefile in the national atlas
set, there's another called hydrogl020 that has linear features instead
They're both huge.

I saved the dbfawk file as hydrogp020.dbfawk in the same directory as the
shape file, so it's specific to the one map layer.
