Last year the drought became a humanitarian crisis, as people dependent on rivers were left without food, water or medicine. However, this year officials are already on alert. At least 62 municipalities in Amazonas state are under a state of emergency and more than half a million people are affected, according to the state Civil Protection Corps. “This is the worst drought to hit the port of Manaus in more than 120 years,” one local said. He said the river level is likely to fall further in the next one or two weeks. The port of Manaus measured the Rio Negro river at 12.66 meters on Friday, surpassing the lowest level recorded last year and still falling rapidly.
Amazon is a freshwater river
The Rio Negro is a major tributary of the Amazon River, the world's largest river by volume. Where the black waters of Negros meet the sandy-colored Solimo reached a record low this week. The port union said last month that grain shipments on the Madeira River, another tributary of the Amazon, were halted due to low water levels. Researchers are once again finding dolphin carcasses in the freshwater river Amazon, which they believe is responsible for thinning the waters. This is why endangered aquatic species are coming into closer contact with humans.
