Hydrology
On the extreme southern boundary of the Tiger Reserve, a dam (Pench Hydroelectric Project) has been constructed on the Pench River. This dam forms the State boundary between Madhya Pradesh and Maharashtra. Because of this dam’s reservoir, a sizeable proportion (54 km²) of the Tiger Reserve on the Madhya Pradesh side becomes submerged after the monsoonal rains. As summer approaches, these areas, from where the water gradually recedes downstream, become lush green meadows attracting high numbers of wild herbivores. During summer, the Pench River dries out leaving small pools of water locally known as "doh" or "khassa", which, besides the Pench reservoir, are the most important sources of water for the animals during this period. Artificial sources of water such as earthen tanks and check-dams (anicuts) also tend to dry out before the month of March, due to the inherent low water retention capacity of the soil. The Reserve management has also set up many hand-pumps and artificial water holes throughout the Reserve to serve as minor sources of water during the pinch summer months.
