Duduma Waterfall

Duduma Waterfall is a 175-metre waterfall on the Machkund River on the border of Koraput district in Odisha and Alluri Sitharama Raju district in Andhra Pradesh, about 70 km from Koraput town near Duduma village. Formed where the river plunges into a deep gorge, it is one of Odisha's highest waterfalls and the source for the Machkund Hydroelectric Project. Surrounded by forested hills, it is known for its wide horsetail cascade and panoramic viewpoints.

Visitors can expect a large waterfall plunging about 175 metres into a deep forested gorge formed by the Machkund River. The site offers viewpoints on the Odisha side overlooking the cascade and gorge, surrounded by hills and dense forest. Access involves walking on uneven paths and steps to viewpoints. There are basic facilities such as parking and small food stalls, with opportunities for sightseeing, photography and short nature walks. Water flow is strongest during and after monsoon.

Formed by the Machkund River which feeds the Machkund (Duduma) Hydroelectric Project, a joint hydroelectric project of the governments of Odisha and Andhra Pradesh developed in the 1950s-1960s, one of India's early major hydroelectric schemes. The waterfall's water is utilized for power generation.

Locally known as Matsya Tirtha, the waterfall is a well-known natural landmark of the Koraput region and holds local significance for nearby tribal communities. It is promoted as a key eco-tourism and nature attraction of southern Odisha.
