Nagarjuna Sagar Dam

Nagarjuna Sagar Dam, at Nagarjuna Sagar in Nalgonda District, Telangana, is one of the world's largest masonry dams. Completed in 1969 across the Krishna River, it forms a huge reservoir and supplies irrigation and hydropower to Telangana and neighbouring Andhra Pradesh. The reservoir lies about 165 km from Hyderabad and can be reached by road via NH565 or by TGSRTC buses to Nagarjuna Sagar. Visitors can walk along the dam viewpoint and see the long line of spillway gates, and when the gates are opened during the monsoon and post-monsoon flood season, the water pouring through them is a major sight. A hydroelectric power station and the surrounding landscaped gardens are also part of the complex. Boats leave from the dam area for Nagarjunakonda, an island in the reservoir, where a museum displays Buddhist relics, sculptures and monuments moved from the valley before it was flooded. The island lies across the border in Andhra Pradesh, and the boat ride takes about an hour each way, so visitors should check the schedule and return time. The best views of the dam and reservoir are from the main viewpoint on the crest and from the boat, and photography is permitted but subject to security restrictions near the powerhouse and gates. A full outing takes three to four hours, and boats run roughly between 9:30AM and 2:00PM, so arriving early is important. The viewpoint is free, and the boat costs about INR 200 to 300, with reduced fares for children. Crowds peak on weekends and during gate-opening periods, when the dam becomes a popular day trip from Hyderabad. Visitors should confirm boat operation in advance, since services can be suspended when water levels are low or weather is poor. Carrying water, sun protection and an identity document is sensible.
