Sanjay Lake Park

Sanjay Lake is an artificial lake developed by Delhi Development Authority (DDA) in Trilokpuri in East Delhi, India, adjoining Mayur Vihar II residential area. Spread over 69 hectares (170 acres) it was developed in the 1970s and also attracts some migratory birds and has many indigenous trees. A well-laid-out fitness track is very popular with walking-enthusiasts.

History
Long before the trans yamuna (now known as East Delhi) area, thus called because it lied across the Yamuna River from the main city of New Delhi, was colonized by the government, this was natural low-lying area, land depression where rainwater collected, which was also fed by excess run-off from a cut in the Hindon River. The area had a number of villages like Patparganj in the floodplains of Yamuna and vast agricultural lands. Eventually, in 1970 this was developed by Delhi Development Authority into a long winding lake.

Initially the lake spread over 89 acres and together with the surrounding park it covered an area of 178 acres. However it was greatly shrunk after DDA started developing the area for its housing colonies, as colonies like Mayur Vihar, Indraprasta Extension (I.P. Extn.), and Patparganj DDA colonies started coming up in the 1980s and its catchment area was largely built over. Similarly, when National Highway 24 (NH 24) was built to connect the national capital to Capital of Uttar Pradesh state, Lucknow, which cut through the lake, and the Nizamuddin bridge was built over the Yamuna and its northern portion was lost and lake was reduced to present 69 hectares (170 acres). In the following decades, as land pressure increased in East Delhi, the lake further shrunk due to unauthorised construction, encroachment and sewage from near by slums.
