The present study was conducted in environs of the sacred grove of Garhwal Himalaya, India, with a view to assess the impacts of sacred groves and forests on the quality and quantity of water and also to assess the effect of seasonality on perennial stream quality. Water samples were collected from three randomly selected stream spots of both the sacred grove dominated by deodar (Cedrus deodara) and the non-sacred patch dominated by oak (Quercus leucotrichophora). Water samples from both patches were within the World Health Organization (WHO) standard limits. Based on an already established water quality index, water quality of both patches was safe for domestic and irrigation purposes but needs treatment for drinking purposes. Results of the present study also showed a very prominent impact of forest type as well as management condition on water quality and quantity. The water discharge from an oak forest shows more consistency than the discharge from a deodar forest. Due to the presence of the sacred grove, the area has become the source of good quality water supply during lean season for the surrounding villages. Water quality and quantity differed along with the change in season. The sacred grove and the existing forest leave a great impression on local dwellers, as due to its presence, local dwellers never run out of water supply during the dry season. As a result, the villagers sincerely want to protect the area for the sake of their own well-being.
