This shows

Vicky's contour-based DEM, clipped to somebody's polygon.
Rivers from the SRTM DEM
Red geology boundaries, showing the Madeira channel.
Heavy blue boundaries for 3 of the 14 sub-basins.
Green stars for 3 of the sub-basin outlets.

Because part of the channel is clipped from the DEM, there are two outlets 6 km apart. We would have to tweak the DEM to make the western sub-basin part of the main Ji-Parana basin. I don't where Vicky's basin boundary came from. Are we sure that the Madiera did not capture that channel?

These are my preliminary figures:
  Rivers 
derived from the CGIAR version of the SRTM 3" (~90m) DEM.

  Same rivers with the 10 stations from Dani's spreadsheet.
              If we use these rivers, we have to move the stations onto
              the river channels.


  Same figure, but insets are color-coded elevations.  The
                dark overlays indicate the places where "sinks" in the
                DEM were filled.  We some effort, DEMs can be tweaked to
                fix these problems.

I will compare this with Vicky's contour-based DEMs.

P.S. Including what, Jeff?  I will try to make the site match your expectations
later today.

 shows a detail of the basin.  I don't think
that SRTM DEM is as good as the topo-map-based DEM.
