Saraswati

                         The river Sarasvati originated from the Har-ki-Dun glacier near Yamunotri in West Garhwal. It joined Yamuna and flowed towards south with the name of Sarasvati. It flowed through Panjab and Haryana where it joined with Ghaggar and other small tributaries. River Sutluj and Shatadru joined the river Saraswati as a tributary at Shatrana. Sarasvati then flowed through Rajasthan , Hakra and Bhawalpur before emptying into the Rann of Kutch via Nara in Sindh province, running parallel to the Indus River. The river Sarasvati, carried the waters of three perennial and numerous seasonal rivers. It was considered as a mighty river in the ancient times.
                 
                  Although the river does not have a physical existence today, there are numerous references to it in the ancient Indian literature of the Vedic period. A part of the river exists now as Ghaggar in Haryana. The present dried bed of the Ghaggar was thus part of a major river, known as Sarasvati.

                  The history calls Sarasvati as the seventh river of the Sindhu Sarasvati river system. Hence it has the name 'Saptsindhu' in the region bounded by rivers Sarasvati in the east and Sindhu (or) Indus in the west.
