The geography of Durg is deeply defined by its primary waterway, which is crucial for both drinking water and agriculture.
* **Shivnath River:** This river is the primary waterway flowing through Durg. It is a major tributary of the Mahanadi River. The Shivnath provides the city's drinking water and is deeply integrated into local religious life, serving as the site for rituals and idol immersions during festivals. * **Local Ponds (Talabs):** Like many traditional Indian cities, Durg has several historic community ponds used for religious ceremonies, particularly during the Chhath Puja festival.
