Which of the following dams is located on the Mahanadi river?

CONCEPT

A dam–river question is solved by matching each named project with the river crossed by its main barrier, not merely with the wider drainage basin.

For a combined-response choice, evaluate every named dam independently; when the condition holds for multiple entries, the combined choice applies.

APPLICATION

1. The Central Water Commission describes Hirakud Dam as built across the Mahanadi near Sambalpur, Odisha.

2. The Central Water Commission’s National Register lists Dudhawa Dam with the river and basin both recorded as Mahanadi.

3. The CWC register lists Ghumarapadar with River ‘Local nalla’ and Basin ‘Mahanadi’, so the basin name does not replace its direct River value.

4. Thus, Hirakud and Dudhawa independently satisfy the stated river association.

CONTRAST

• Hirakud alone omits the independently verified Dudhawa match.

• Dudhawa alone omits the independently verified Hirakud match.

• Ghumarapadar alone does not account for the two independently verified matches.

• None of the above conflicts with the two verified matches.

CROSS-CHECK

Two individually named dams satisfy the condition, so the result is More than one of the above.
