Mohan, 1992, [https://books.google.com/books?id=Z8FIAAAAYAAJ Environment and Urban Development: A Critical Evaluation of Slums].</ref> is a 791 meters<ref name=rg1/> or roughly 800-yard long [[Barrage (dam)|weir]] across [[Yamuna|Yamuna River]] opened in 1874.

==History==
The barrage and Agra canal were opened in 1874 by the [[British Raj]] for the purpose of [[irrigation]] and water navigation from [[Delhi]] to [[Gurgaon]], [[Mathura, Uttar Pradesh|Mathura]] and [[Agra District|Agra]] districts, and [[Bharatpur State]]. Navigation stopped in 1904.<ref name=okhla2>{{cite EB1911|wstitle=Agra Canal}}.</ref> It was built seven-feet higher than the summer level of the river.<ref name=okhla2/>

The Yamuna, from its origin at [[Yamunotri]] to Okhla barrage, is called Upper Yamuna which is managed by Upper Yamuna River Board created in 1995.<ref name=okhla12>2015, [https://books.google.com/books?isbn=8123020066 INDIA 2015], New Media Wing.</ref><ref name=okhla11>[http://uyrb.nic.in/ Upper Yamuna River Board] {{Webarchive|url=https://web.archive.org/web/20100117191330/http://uyrb.nic.in/ |date=17 January 2010 }} Official website.</ref> Yamuna flows for 48 km in Delhi, including 22 km from [[Wazirabad barrage]] where it enters Delhi to Okhla barrage after which it enters Haryana.<ref name=total1>[spaenvis.nic.in/index1.aspx?lid=2284&mid=1&langid=1&linkid=550 YAMUNA FLOOD PLAIN - ENVIS Center on Human Settlement's] 30 June 2016.</ref><ref name=okhla8>Joginder Singh, 2010, [https://books.google.com/books?id=qGmpz0IrNVIC&pg=PA504&dq=okhla+barrage+name&hl=en&sa=X&ved=0ahUKEwiL9rTPjpXYAhXBQo8KHY7yAeoQ6AEIQjAF#v=onepage&q=okhla%20barrage%20name&f=false India, Democracy and Disappointments], Page 504.</ref><ref name=okhla9>Sharad K.
