Nagarjuna Sagar Reservoir

Nagarjuna Sagar is a massive masonry dam and reservoir built across the Krishna River on the border of Telangana and Andhra Pradesh. It is one of the world's largest masonry dams, standing 124 meters tall with a length of over 1.6 kilometers. The reservoir creates a vast artificial lake and serves as a major source of irrigation and hydroelectric power. It is a significant tourist attraction known for its scenic views, especially during the monsoon when gates are open, and provides access to the historic Nagarjunakonda island.

Visitors can expect to see the massive dam structure with 26 crest gates and enjoy panoramic views of the Krishna River valley. During the monsoon season, the opening of gates creates spectacular waterfalls. The site offers boating facilities operated by Telangana Tourism, providing access to Nagarjunakonda island which houses an archaeological museum with Buddhist relics. The surrounding area features dense greenery and the reservoir backwaters. Facilities include parking areas and basic amenities, though visitors should be prepared for limited infrastructure in some areas.

Construction began in 1955 and was completed in 1967. It was one of the first major irrigation projects initiated by independent India as part of the Green Revolution, termed a 'modern temple'. The reservoir submerged the ancient Buddhist settlement of Nagarjunakonda, which was the capital of the Ikshvaku dynasty in the 1st and 2nd centuries CE. Artifacts and monuments were relocated to higher ground before flooding.

The dam represents a significant achievement in post-independence Indian infrastructure development. The submerged Nagarjunakonda site holds immense cultural importance as a center of Buddhist learning and art. The relocated museum on Nagarjunakonda island preserves Buddhist sculptures, inscriptions, and relics including items believed to be associated with Gautama Buddha.
