About Nagarjuna Sagar Dam
The Nagarjuna Sagar Dam, built across the Krishna River, is one of the largest masonry dams in the world and a proud landmark of Andhra Pradesh and Telangana. Located between Nalgonda district (Telangana) and Palnadu district (Andhra Pradesh), the dam is not only a massive engineering achievement but also a lifeline for irrigation, drinking water, and power generation.
Completed in 1967, the project was a symbol of independent India’s focus on large-scale infrastructure and has since played a crucial role in transforming the agricultural landscape of the Krishna basin.
Architecture
The Nagarjuna Sagar Dam is renowned for its sheer size and design. Constructed as a masonry dam, it stands 124 meters (407 ft) high and stretches across 1.6 kilometers (5,315 ft), making it one of the longest dams in India.
The reservoir, known as Nagarjuna Sagar Reservoir, is among the largest in the country with a gross storage capacity of 312 tmc ft (thousand million cubic feet). The dam has 26 crest gates that regulate the flow of the Krishna River, releasing spectacular water flows during monsoon, which have become a tourist attraction in themselves. It also houses a hydroelectric power plant with a capacity of nearly 815 MW, contributing significantly to the power supply of Andhra Pradesh and Telangana.
Importance and Benefits
The dam has been a boon for agriculture, irrigating millions of acres in Guntur, Prakasam, Nalgonda, and Krishna districts, ensuring year-round cultivation of crops like paddy, cotton, and pulses. It provides drinking water to several towns, including Hyderabad, and is vital in meeting the growing demands of urban areas.
The hydropower generation from the project has reduced dependency on thermal energy, making it an eco-friendly contributor to regional development. Beyond its utility, the dam stands as a symbol of progress and cooperation between Andhra Pradesh and Telangana.
Tourism and Attractions
Nagarjuna Sagar is not only about engineering but also about heritage and natural beauty. The Nagarjuna Sagar Reservoir, with its vast expanse of blue waters surrounded by lush green hills, is a scenic spot that draws tourists year-round.
Boating facilities allow visitors to reach the Nagarjunakonda Island, which houses a museum and excavated Buddhist sites dating back to the 2nd–3rd century CE. During the monsoon, when the gates are lifted, the sight of water gushing down in massive volumes creates a breathtaking spectacle, making it one of the most visited tourist attractions in both Andhra Pradesh and Telangana.
