caption_attribution_description: English: Ottu reservoir, Sirsa district, Haryana, India. This is a reservoir on the Ghaggar-Hakra river. It was formerly called Dhanur lake.
context_page_description: The Ghaggar-Hakra River is an intermittent river in India and Pakistan that flows only during the monsoon season. The river is known as Ghaggar before the Ottu barrage and as the Hakra downstream of the barrage. The Hakra river is hydraulically connected to the Nara River provided it has adequate flow to maintain surface flow. After the construction of the Otu Barrage, the downstream Hakra river dried up fully but subsurface flow is maintained to the Nara river which becomes later the delta channel of the Indus River before joining the sea via Kori Creek in Gujarat state.
  A paper published in Nature journal in 2017, asserts that the Ghaggar-Hakra palaeochannel was being fed by the himalayan Sutlej river. The initial abandonment by the river Sutlej started about 15,000 years ago with complete avulsion to its current course shortly after 8,000 years ago.
  The basin is classified in two parts, Khadir and Bangar, the higher area that is not flooded in rainy season is called Bangar and the lower flood-prone area is called Khadar.
context_section_description: The Ghaggar is an intermittent river in India, flowing during the monsoon rains.  It originates in the village of Dagshai in the Shivalik Hills of Himachal Pradesh at an elevation of 1,927 metres (6,322 ft) above mean sea level and flows through Punjab and Haryana states into Rajasthan;  just southwest of Sirsa, Haryana and by the side of Talwara Lake in Rajasthan.
  Dammed at Ottu barrage near Sirsa, Ghaggar feeds two irrigation canals that extend into Rajasthan.
