Khandoli Dam (Hindi: खंडोली डैम) is a dam located 10 km North-East of Giridih town towards Bengabad in Jharkhand, India. Khandoli is also a village at the foot of the Khandoli hill. The reservoir of the Khandoli dam provides water supply to more than one lakh residents of the Giridih town. It is an important tourist spot in the state of Jharkhand.
The Khandoli hill has a peculiar shape of a saddle and is made up of Granitoid gneiss. The peak of khandoli hill appears similar to a volcanic cone and has a great saddle consisting of massive boulders attached to it. Recently the urban development department has made plans to desilt the Khandoli lake after decades.
Every year thousands of migratory birds arrive at Khandoli lake by travelling thousands of kilometres from northern Asia, Himalayan belt, Africa and Australia. Great cormorant, Siberian duck, Siberian crane, brahminy shelduck (ruddy shelduck), bar-headed goose, mallard and several other species migrate to the dam for breeding. The migration of birds generally begins from the second week of November every year for a warmer climate and return around March. As many as forty different species of birds come to Khandoli but their number has reduced over the years mainly due to pollution and poaching. Some animals such as rabbit, Guinea pig, peacock, owls etc. are also kept in cages in the amusement park.
Khandoli has been developed as a tourism attraction by district tourism department. The number of tourists increase in the winter months for bird-watching due to the presence of migratory birds in the area. An amusement park spread over 6 acres (2.4 ha) is built near the lake which offers joy rides in toy train and swings. Elephant and camel safaris and numbers of other amusement facilities are available. A canteen is available for convenience of the tourists. A watch tower and 600 feet high hillock offers a panoramic view of Khandoli site.
