The short answer
Nagarjuna Sagar Dam: what visitors should know first
Yes, it anchors any visit. The wall, the 26 crest gates and the reservoir view are impressive in any season, but the spectacle of open gates happens only in years of strong inflow, so treat that as a bonus rather than a plan.
History and context
The story behind Nagarjuna Sagar Dam
Surveys under the Nizam's government began in 1903, but the project only took shape after independence. Nehru laid the foundation in December 1955, and the dam was completed in 1967, with water first released to the canals that August. The power units were commissioned between 1978 and 1985.
The dam straddles the border between what is now Telangana and Andhra Pradesh and is operated jointly by the two states.

Why it matters
Why Nagarjuna Sagar Dam is worth your time
Construction was formally launched in December 1955 and the dam was completed in 1967. Jawaharlal Nehru's phrase for such projects, temples of modern India, is quoted at the site by tourism writers. It irrigates land in both Telangana and Andhra Pradesh through the right (Jawahar) and left (Lal Bahadur Shastri) canals and feeds a hydroelectric station of about 816 MW, with more capacity on the canals.
It also explains everything else you will see here. The reservoir drowned the Ikshvaku-era valley of Vijayapuri, so the monuments of Nagarjunakonda were moved to an island and to higher ground. The township, the tourism boats and even the Buddhist theme park are all by-products of the dam. Seeing it first makes the rest of the day make sense.
Highlights
What not to miss
- 01
The crest gates
Twenty-six gates run along the top. Look at them even when closed to gauge the scale of the structure.
- 02
Open-gate days
When flood inflows force a release, the discharge draws large crowds. Check local news before planning a trip around it.
- 03
Reservoir view
The lake side shows how far the water reaches back and why a boat is needed to reach the island museum.
Plan your visit
How to experience it
Approach the dam as a piece of engineering rather than a sight to tick off. The structure is about 124 metres high from its deepest foundation and roughly 1.55 km long, built of stone masonry rather than concrete, and has 26 crest gates along the top. From the road you see the long grey face and the spillway; from the reservoir side you see how much water it holds back.
Timing matters more than anything else. In most years the gates stay shut and the visit is a calm half hour of looking at the structure and the lake. In a heavy monsoon the gates are lifted and the discharge becomes a crowd-pulling event. In 2025, 14 of the 26 gates were raised in late July, reported as the first July opening in 18 years. Do not count on this; reservoir levels are the deciding factor and they change year to year.
Combine the dam with the boat jetty and Buddhavanam, which lie within a short drive on the same side of the township. Avoid weekends in the open-gate season if you dislike crowds, and expect traffic control around the viewpoints.
Plan with confidence
Small decisions that make the visit easier.
- Confirm the day's access to the dam top before driving to the viewpoint
- Carry water, a hat and sunglasses; shade is scarce
- Check local news for gate-opening dates in August to October
- Avoid weekends during open-gate periods if you dislike crowds
Know before you go
Timing, access and comfort
- Area
- Nagarjuna Sagar town, on the Nalgonda (Telangana) and Palnadu (Andhra Pradesh) border
- Time needed
- 1 to 2 hours
- Best time
- Late morning to early evening; August to October if the gates are open, November to February for comfort
- Walking level
- Easy
- Senior comfort
- Viewing is largely from roads and level vantage points, so walking is modest. There is little shade on the dam top, and wind and glare can be tiring, so carry a hat and water.
- Tickets and access
- Access to the dam top and nearby viewpoints can be restricted at short notice for security or flood reasons. Check with local police or the tourism office on the day rather than relying on a fixed rule.

Are the dam gates always open?
No. They open only when reservoir levels demand it, which is some monsoons and not others. Do not plan a trip around a gate opening without checking recent news.
Is the dam in Telangana or Andhra Pradesh?
Both. It spans the Krishna between Nalgonda district in Telangana and Palnadu district in Andhra Pradesh, and the two states operate it together.
How long should I allow?
One to two hours covers the dam, viewpoints and a look at the reservoir. Add more if you plan to take a boat trip.
