The
Balikh River is a
perennial river that originates in the spring of
'Ayn al-'Arus in
Syria. It flows due south and joins the Euphrates at the modern town of
Ar-Raqqah. After the
Khabur River, the Balikh is the largest tributary to the Euphrates on Syrian soil. It is an important source of water and large parts have recently been subjected to canalization.
