The dam project is a joint venture between the states of Karnataka and Andhra Pradesh.
The reservoir area spans approximately 378 square kilometers at full capacity.
It is the first major multipurpose river valley project commissioned in post-independence India.
The structure is designed to irrigate nearly 400,000 hectares of farmland across two states.
The dam's spillway is equipped with 33 large vertical lift gates to manage flood discharge.
The reservoir submerges the ancient site of Hampi during its maximum water levels.
Tungabhadra Dam is a large multipurpose gravity dam constructed across the Tungabhadra River in the Hospet taluk of Vijayanagara district, Karnataka. Completed in 1953, the structure is built of rubble masonry and stands as one of the largest dams in Southern India. It serves as a vital irrigation source for the arid regions of North Karnataka and neighboring Andhra Pradesh, facilitating large-scale agriculture. The dam features an extensive reservoir, often referred to as Pampa Sagara, which has a storage capacity of approximately 133 thousand million cubic feet. The site includes the Tungabhadra Dam Gardens, located at the base, which are landscaped with fountains and seasonal flora. Water release from the 33 spillway gates is a major seasonal event, typically occurring during the monsoon period when the reservoir reaches full capacity. The dam complex also includes a small hydroelectric power station.
The elevated viewing points in the ornamental gardens below the dam.
Carry government-issued photo identification as security checks are frequently conducted at the entry points.
Bring binoculars to spot diverse bird species near the reservoir banks.
Ensure you have adequate sun protection, as the dam top offers very little shade.
Do not attempt to walk into unauthorized areas near the hydroelectric plant or spillway gates.
Spillway gates are typically opened between August and October, depending on monsoon inflow.
Photography is strictly prohibited on the dam wall; follow all signage regarding restricted zones.
