Najafgarh jheel

Najafgarh Lake, Najafgarh Marsh or Najafgarh Jheel (Jheel in Hindi means a lake), fed by Sahibi River, used to be a vast lake in the south west of Delhi in India near the town of Najafgarh from which it takes its name. It was connected to the river Yamuna by a natural shallow nullah or drain called the Najafgarh nullah. However, after the 1960s the Flood Control Department of Delhi kept widening the Najafgarh drain in the pretext of saving Delhi from floods and eventually quickly drained the once huge and ecologically rich Najafgarh lake completely. Rainwater accumulating in the Najafgarh lake or jheel basin had been recorded to have occupied more than 300 square kilometres (120 sq mi) in many years before its unfortunate draining.

With recent advances in ecological understanding it has become clear that draining of this vast lake affected the entire climate of this important region that is India's capital territory of Delhi and its neighborhood, it also led to the underground water-table going down leading to water scarcity for this densely populated region. However, at the time of the draining of the lake in the 1960s or in the decades that followed the issue of destroying the rich wetland ecosystem and wildlife habitat of the lake, its ecological value and its value as a water reservoir recharging the local water table in the dry months and the effect of draining this vast lake on local climate largely went unnoticed and undiscussed as the general public, the media and news agencies or the related environment departments were largely unaware and oblivious of what was happening and its long-term effects. Even now the fact that a vast lake ever existed here in the region and the current need for resurrecting it remains largely an unknown little discussed issue. The complete draining of the lake caused the great loss of a rich wetland ecosystem and wildlife habitat and led to the water-table in the entire region to go down which has in turn led to the area becoming more and more arid. There have been some plans since to at least resurrect a much smaller lake in the area. Most of the Najafgarh jheel basin lands have increased many folds in their value owing to them coming within Delhi, India's capital territory and are under ownership of farmers who may want to make a fast buck selling them to developers who want to convert the former lake basin into housing complexes as has already been happening with major housing colonies coming up in the region. If Najafgarh drain, which was built to drain the original Najafgarh lake or jheel, ever breaches its wide embankments it will flood these developed lands and housing colonies owing to them spread all over the former low lying jheel or lake basin.
