"MANAUS, Brazil (AP) — One of the Amazon River’s main tributaries has dropped
to its lowest level ever recorded, Brazil’s geological service said Friday,
reflecting a severe drought that has devastated the Amazon rainforest and other
parts of the country.
The level of the Negro River at the port of Manaus was at 12.66 meters on
Friday, as compared with a normal level of about 21 meters. 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 Negro River’s 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."
