The area is criss-crossed by numerous seasonal streams and "nalas". The Pench River flowing through the central line of the reserve is dry by the end of April but a number of water pools locally known locally as "dohs" are found, which serve as waterholes for wild animals. A few perennial springs also exist in this area. However, the water sources are not suitably distributed, hence large area remains unused by the wild animals. The Pench reservoir at the center of the reserve is the only major water source during pinch period.
