This study aims to show the Indirect effect of SARS Covid-19 on the River water of Ganga flowing in Uttrakhand. The Ganga River has shown a positive sign of quality improvement on many parameters due to the 68 days’ nationwide lockdown tobreak the spreading chain of the Covid-19 pandemic in India. During that time, various types of industrially contaminated water and sewage water flowing by the hotel industry were closed as shown in the Abstract figure. The impact could be seen in reduced Biological oxygen demand (BOD) and chemical oxygen demand (COD) and total coliform count and faecal coliform count also found in decreased in number compared to previous studies results from the outcome of these collection points (fig. 1). This paper concludes that River can be rejuvenated if the rule made are strictly followed.
