The Sarasvati, celebrated in Vedic hymns thousands of years ago, dried up and vanished, leaving behind only a ghostly paleochannel etched into the geology of Rajasthan. In the twentieth century, Indian engineers traced that channel and built a canal on top of it -- not to resurrect a sacred river, but to irrigate one of the driest landscapes on Earth. The Indira Gandhi Canal stretches 649 kilometers from the Harike Barrage in Punjab to the desert outpost of Mohangarh in Jaisalmer district, carrying Sutlej and Beas river water southwest through increasingly arid terrain. Because it follows the Sarasvati's natural incline, the entire system operates by gravity alone, requiring no pumping stations along its length. That fact still astonishes hydraulic engineers who study it.

Planning began in the 1950s, and construction started at the Harike Barrage in Firozpur district, where the Sutlej and Beas rivers converge. From there, the Raja...

Villages depended on erratic monsoon rains and deep wells that often ran dry. The canal changed the ecology of entire districts. In Hanumangarh and Sri Ganganagar, formerly barren land...
