The Hathni Kund is a concrete barrage located on the Yamuna River in Yamuna Nagar district of Haryana state, India. It was constructed between October 1996 and June 1999 for the purpose of irrigation. It replaced the Tajewala Barrage {{Convert|3|km|mi|0|abbr=on}} downstream which was constructed in 1873 and is now out of service. The barrage diverts water into the Western and Eastern Yamuna Canals. The small reservoir created by the barrage also serves as a wetland for 31 species of waterbird.{{cite journal|last=Tak|first=Prakash C.|author2=Jagdish P. Sati|author3=Anjum N.

Plans to replace the Tajewala Barrage had been in the works since the early 1970s but an agreement between the governments of Haryana and Himachal Pradesh (which share the water it diverts) was not made until July 1994.{{cite web|title=Hathnikund Barrage completion by April .'99|url=http://www.indianexpress.com/ie/daily/19980505/12551514.html|publisher=Express News Service|access-date=10 July 2011}}{{dead link|date=October 2017 |bot=InternetArchiveBot |fix-attempted=yes }} Although the barrage was completed in late 1999, it was not operational until March 2002 because of work delays.{{cite web|title=Conclusions|url=http://planningcommission.nic.in/reports/sereport/ser/wjc/wjc_ch5.pdf|publisher=Indian Planning Commission|access-date=10 July 2011}} The barrage is {{Convert|360|m|ft|0|abbr=on}} long and its spillway is composed of ten main floodgates along with five undersluices on its right side and three on its left. The maximum discharge of the barrage is {{Convert|28200|m3/s|ft3/s|0|abbr=on}} (1 in 500 year flood).{{cite web|title=Baseline Parameters of JWC|url=http://planningcommission.nic.in/reports/sereport/ser/wjc/wjc_ch3.pdf|publisher=Indian Planning Commission|access-date=10 July 2011|page=31}}

Due to this barrage, 90% of the river volume is diverted leaving only 10% in the original bed flow.{{Cite book |last=Kumar |first=Bidisha|last2= James |first2=George |title=Brill's Encyclopedia of Hinduism Online |publisher=Brill |year=2018 |editor-last=Jacobsen |editor-first=Knut A. |chapter=Yamunā |editor-last2=Basu |editor-first2=Helene |editor-last3=Malinar |editor-first3=Angelika |editor-last4=Narayanan |editor-first4=Vasudha}}
