The Indus system comprises the main Indus, Jhelum, Chenab, Ravi, Beas and Sutlej. The basin is mainly shared by India and Pakistan with a small share for China and Afghanistan.
Jhelum and Ravi join Chenab, Beas joins Sutlej, and then Sutlej and Chenab join to form Panjnad, 10 miles north of Uch Sharif in Muzaffar Garh district.
The combined stream runs southwest for approximately 44 miles and joins the Indus River at Mithankot.
Sutlej River:
The ancient name of Sutlej River is Zaradros (Ancient Greek) Shutudri or Shatadru (Sanskrit).
It is the longest of the five tributaries of the Indus River that give Punjab (meaning “Five Rivers”) its name.
It rises on the north slope of the Himalayas in Lake La’nga in southwestern Tibet.
