"Chennai, an Indian City of Nearly 5 Million, Is Running Out of Water"

"The water is almost gone.

Satellite photographs reveal the stark shrinking of one of the main rain-fed reservoirs that serves Chennai, one of the biggest cities in India.

In one image, taken by satellite on June 15 last year, the city’s largest reservoir, Lake Puzhal, resembles a dark blue ink-stain amid a densely crowded cityscape.

In another, taken on Sunday, exactly a year later, the lake is a small grey fraction of its former self."
