Hermann,
Duh! Of course!
Thanks,

Indeed.
What command could I pass to r.mapcalc that would clip
the raster map to the basins themselves

IMHO g.region is the choice ...
Helmut,
Thanks for the clarification.

Why would one want to do this, compared to leaving the extent as
detected during import?

Use cases might be:

g.region and r.region are different tools:
g.region - Manages the boundary definitions for the geographic region.

r.region - Sets the boundary definitions for a raster m
