This political map of Indian states and major rivers is offered
for reference purposes only, and is not approved by the Indian
authorities. It is not to scale, nor does it represent the
borders of India as defined by the Indian Government (In any
case, the wiggly bits around Bangladesh are quite inaccurate).
Carrying a copy of this map with you into India could result
in some uncomfortable philosophical discussions with the men
and women at the customs dept.
