Haryana has no perennial rivers. The important rivers are Yamuna, the
Saraswati and the Ghaggar. Several small streams flows through the
state they are the Markanda, the Sahibi and Indori. Yamuna is the most
important river in the state. It has its source in the hills at
Kalesar and is the source of irrigation for large tracts in the districts
of Ambala, Kurukshetra, Karnal, Hissar and Rohtak through the western
Yamuna canals. The river Saraswati begins in the large depression at Kalawar
in the north of the Mustafabad Pargana of Jagadhri. The Ghaggar rises
in the outer Himalayan ranges between the Yamuna and the Sutlej.
