The lake was constructed by the Delhi Development Authority (DDA) in the 1970s.
It is one of the largest lakes in Delhi, spanning approximately 52 acres.
The park is officially categorized as a 'District Park' under Delhi's land-use zoning.
The area is known to attract migratory birds during the winter months, including ducks and waterhens.
A portion of the lake is surrounded by the Sanjay Lake forest area, which contains over 17,000 trees.
The site was historically part of the floodplains of the Yamuna River.
Sanjay Lake Park is a sprawling 52-acre man-made reservoir located in the Trilokpuri area of East Delhi. The lake acts as a significant urban wetland, serving as a seasonal habitat for various migratory bird species. The surrounding parkland features paved jogging tracks, dense forest patches, and designated open-air exercise equipment stations. It is part of a larger eco-development project designed to provide a green lung for the densely populated Mayur Vihar residential zones. The water body is fed primarily by rainwater harvesting and recycled water systems. Boating facilities are provided on the lake, catering to local visitors and families. The park is managed by the Delhi Development Authority (DDA) as part of their urban forestry initiatives.
The lakeside vantage point near the boat jetty offers the most unobstructed views of the water and skyline.
Bring insect repellent, as the lake's proximity to water and dense foliage increases mosquito activity.
Visit during the early morning hours to observe the highest diversity of migratory bird activity.
Carry your own drinking water, as facilities within the park are limited.
Avoid visiting during the peak heat of summer afternoons, as the park offers limited shade in open sections.
Avoid feeding birds or wildlife and refrain from littering to maintain the integrity of the wetland ecosystem.
