The Jalaput Dam built across the Machkund River of Orissa stands as a boundary between the states of Orissa and Andhra Pradesh. The dam is situated near Ondra Gadda in the district of Vishakapatnam and is placed along the Mudugal hills. The dam has a steep fall along it known as the Duduma Falls. The Jalaput Dam has been functioning from the year 1955 and it holds around 34.273 TMC of water under the Machkund Hydro-Electric Scheme (MHES), down stream.

The name Jalaput is basically a tribal name which has acquired its name putting together the two words Jal and Put. The word Jal means water and Put means store house. As Jalaput Water Reservoir provided water to many of the local tribes the dam came to be known as the Jalaput Dam.

Jalaput is also a village, bordering the two states, Orissa and Andhra Pradesh. This bridge makes a distinction between the two states. The bridge in the Visakhapatnam district of Andhra Pradesh is known as LF, whereas the bridge in Koraput district of Orissa is called the RF. The Jalaput RF Bridge belongs to the Koraput District, while the LF Bridge belongs to the Visakhapatnam district of Andhra Pradesh. Before the Jalaput Dam was constructed, this bridge was known as Tentaput. Many tribal villages are still seen along the bridge. The triangular shape of the hydro-electric project is formed by Jalaput, Machkund and Onukadelli. This hydro-electric power station in Jalaput provides electricity to Vishakhapatnam and Vijaywada in Andhra Pradesh and Jeypore in Orissa.
