A common Indian has a lot of faith in the Saraswati river.  Where a person is easily introduced to the rivers Ganga, Yamuna, Godavari, Ravi, Sutlej, Beas, Narmada, Kaveri, Kosi, Gandak, Brahmaputra, Godavari etc., whereas Saraswati river is generally known to every person in today's time. 

 It cannot be said with certainty whether there is some information or more information.  The first opportunity to learn about the Saraswati river is often in the school curriculum when mentioning rivers or BC India in social sciences or other subjects.  I was introduced myself to Saraswati river, some from school books and some due to the interest of elders in the family in Indian culture, Havan etc.  When my grandmother used to take bath and worship in the month of Kartika, while lighting a lamp to Tulsi in the morning, she used to take names of many rivers in the same rhythm, in the same hymn.  

The name of river Saraswati was also mentioned in his pronunciation.  There is a famous shrine of Ramdevra near my village, where a line comes in the aarti - 'Ganga, Jamuna, Bahe re Saraswati, Ramdevji babo bathe.  In this way Saraswati river is deeply associated with folk life and folk faith.  Experts have different opinions about Saraswati river.  But if we make an overall assessment, by three or ten thousand years BC, this river was full of water, iceberg It used to flow in the form of a big river starting from  Then it traveled from east to west passing through present-day Himachal Pradesh, Punjab, Haryana, Rajasthan, Gujarat and Sindh to the Arabian Gulf.  

When the flow decreased, the rivers flowing throughout the year or for some time in its flow area came to be known by different names.  The historical names prevalent in some areas of the Saraswati river are still intact today.  It is believed that at one time it used to flow between Yamuna and Sutlej, then due to earthquake etc., its course changed and later it disappeared.  

It is believed that when Awad Mata ji arrived from Sindh with her sisters and brother in the Mandh region, she crossed the Hakra river.  It is believed that Awad Mata ji ended it after not giving way to the Hakra river by collecting its huge water body.  

This Hakra river, which The ocean was also called, then it was the last part of the Saraswati river, which used to meet in the Arabian Gulf.  Many stories of the Rig Vedic and Mahabharata periods are also associated with it.
