In Brazil's Amazon, rivers fall to record low levels during drought
The Negro River, the Amazon’s second largest tributary, on Monday reached its lowest level since official measurements began near Manaus 121 years ago. The record confirms that this part of the world´s largest rainforest is suffering its worst drought, just a little over two years after its most significant flooding. The Negro River drains about 10% of the Amazon basin and is the world's sixth largest by water volume.
