The Ganga Canal is the foundational reason Sri Ganganagar exists. Built in the 1920s by Maharaja Ganga Singh of Bikaner, it carries water from the Sutlej River (in what is now Pakistani Punjab) across the desert fringe into Rajasthan, converting arid land into some of the most productive farmland in the state. The city grew up around the canal's administrative headquarters.
The canal itself runs through and around the city, with walking paths alongside in places. It's not a dramatic tourist sight but an interesting piece of irrigation history — the first major canal in Rajasthan and a model for later large-scale projects. The agricultural landscape it sustains (wheat, cotton, kinnow orchards) is visible for miles in every direction.
