Bhalswa Horseshoe Lake, or Bhalswa Jheel, is a lake in northwest Delhi, India. It was originally shaped like a horseshoe. However, over the years half of it was used as a landfill area. Now a low income housing colony, an extension of the nearby town of Bhalswa Jahangir Pur has been built on it, destroying the once excellent wetland ecosystem and wildlife habitat of the region which once played host to scores of local and migratory wildlife species, especially waterbirds, including waterfowl, storks and cranes.
This horseshoe lake was originally formed when the nearby River Yamuna left behind one of its meandering loops here when it changed course over the years and is now channelled through more defined and fortified embankments and dykes to defend modern Delhi from floods.
On the west side of the lake on the landfill-reclaimed land stands a housing colony. On the east side is a plantation of a few acres of acacia, babool and keekar trees, offering some habitat to local remnant wildlife.
