you might look at the r.watershed help page. at the end of the NOTES section is some hints about "To isolate an individual river network" using v.net.iso, etc. http://grass.osgeo.org/grass64/manuals/html64_user/r.watershed.html that was based on some emails which can be found in the mailing list archives.
