You can extract only those features that have Census Feature Class Codes (CFCC)
H01 (shoreline of perennial water feature) or H02 (shoreline of intermittent 
feature) by using extract.line (GRASS4.0) or m.in.stf1.tape (GRASS4.1). If you
are unfamiliar with the usage of these tools, feel free to write me directly.
