[<< wikipedia] Silala River
The Silala is an aquifer and river arising from springs in Bolivia, and flowing into Chile.
The division of the flow from this water body has been a matter of controversy between the two nations, Chile claiming that the present route makes it an international river, while Bolivia denies there is a river and asserts that the Silala ‘springs’ would not flow to Chile if not for the construction of canals over a hundred years ago.
