In the east, the ancient Saraswati (or Ghaggar-Hakra) river ran parallel to the Indus . . . Towards the end of the Indus Valley civilization, the ancient Saraswati had totally dried up and its original tributaries were captured by two other mighty rivers . . .

Many episodes of the Rig-Veda take place along the sacred Saraswati.
