river, northern India. The Ghaggar rises in the Siwalik (Shiwalik) Range (Siwalik Range), in northwestern Himachal Pradesh (Himāchal Pradesh) state and flows about 200 miles (320 km) southwest through Haryana (Haryāna) state, where it receives the Saraswati River. It eventually dries up in the Great Indian (Thar) Desert (Thar Desert). Just southwest of Sirsa it feeds two irrigation canals that extend into Rajasthan (Rājasthān) state. The Ghaggar was probably once an affluent of the Indus River. Its seasonal flow is dependent on monsoonal (seasonal) rainfall.
