Large part of agriculture in Rajasthan depends upon rainfall. There are various regional complexities from the point of view of availability of water for irrigation. Underground water is available in some parts of Rajasthan, but in some places it is done only with the assistance of stream water. Rivers like Chambal, Mahi, Ravi, and Beas are supplying water for such causes. Districts like Ganganagar, Bikaner, Jaisalmer and Jodhpur are getting water supply from Indra Gandhi Canal, whereas river Chambal is supplying water to Kota, Bundi and Sawai Madhopur.
