One of the Amazon River’s main tributaries has dropped to its lowest level ever recorded Brazil’s geological service said on Friday.

The Negro river's low level reflects has been caused by a severe drought that has devastated the Amazon rainforest and other parts of Brazil.
The level of the river at the port of Manaus was at 12.66 metres on Friday, as compared with a normal level of about 21 metres. It is the lowest since measurements started 122 years ago. The previous record low level was recorded last year, but toward the end of October.
The water level might drop even more in coming weeks based on forecasts for low rainfall in upstream regions, according to the geological service's predictions. Andre Martinelli, the agency's hydrology manager in Manaus, was quoted as saying the river was expected to continue receding until the end of the month.
Water levels in Brazil’s Amazon always rise and fall with its rainy and dry seasons, but the dry portion of this year has been much worse than usual. All of the major rivers in the Amazon basin are at critical levels, including the Madeira River, the Amazon River’s longest tributary.
The Negro River drains about 10% of the Amazon basin and is the world’s sixth-largest by water volume. Manaus, the biggest city in the rainforest, is where the Negro joins the Amazon River.
For locals, the drought has made basic daily activities impossible. Gracita Barbosa, 28, works as a cashier on a floating shop on the Negro River. She’s out of work because boats that once stopped there can no longer navigate the river due to the low water levels. Barbosa can no longer bathe in the river and now has to travel longer distances to collect drinking water.
