The water divide between the Indus and the Ganga drainage systems passes through which state?

- B.Haryana
- C.Rajasthan
- D.Uttar Pradesh
Show answer
Explanation
The correct answer is B, Haryana. A low, almost imperceptible divide runs through Haryana, roughly from the Shivalik near Ambala and Kurukshetra down to the Aravalli ridge near Delhi. Streams east of it flow into the Yamuna and so into the Ganga system, while those west of it, the Ghaggar and its tributaries, belong to the old Indus drainage and die out in the sands of Rajasthan.
Option A, Punjab, lies wholly within the Indus basin, drained by the Sutlej, Beas and Ravi. Option C, Rajasthan, has the largest inland drainage area of any state, but the Indus and Ganga divide does not run through it; its own divide is the Aravalli. Option D, Uttar Pradesh, lies wholly in the Ganga basin. The fact worth remembering is that Haryana is the meeting ground of the two great river systems of northern India, which is also why the state has so little surface water of its own and depends on canals.
