Dolphins dying once again in Amazon lake made shallow by drought

The carcass of a baby dolphin lay on the sand bank left exposed by the receding waters in an Amazon lake that has been drying up in the worst drought on record.

Scientist recovered the dead animal on Wednesday and measured water temperatures that have actually been increasing as the lake's. level drops. In last year's drought, more than 200 of the. threatened freshwater dolphins died in Lake Tefe from extreme. water temperatures.

We've discovered numerous dead animals. Last week, we discovered one a. day on average, stated Miriam Marmontel, head of the dolphin. job at the Mamiraua Institute for Sustainable Advancement.

We're not yet associating the deaths with modifications in water. temperature levels, however with the worsening of the proximity in between. human populations, generally fishermen, and the animals, she stated.

With branches of major rivers in the Amazon basin drying up. in this year's important dry spell, the lake connected to the. Solimoes River has actually diminished, leaving less room for the dolphins in. their preferred habitat.

The lake's main channel is 2 meters (6.5 feet) deep and. approximately 100 meters broad, and it is utilized by all the boat traffic,. from canoes to heavy ferries, Marmontel stated. 2 dolphins were. eliminated recently when boats encountered them in the shallow water.

No one believed this dry spell would come so rapidly or. envision that it would surpass in 2015's drought, fisherman. Clodomar Lima stated.

While the dolphin deaths are nowhere near to last year's. toll, the dry season has more than a month to go and water. levels will continue to decrease, the scientist said.

And it is not simply the unusual dolphin species that are. suffering. Riverine communities across the Amazon are stranded. by the absence of transport on waters too shallow for boats, and. their floating homes are now on strong ground.

Even homes built on stilts over water are now high and dry. a distance from the river shore.

Lake Tefe resident Francisco Alvaro Santos said it was the. very first time ever that his drifting house ran out the water.

Water is whatever to us. It becomes part of our every day lives,. the ways of transport for everybody who live here. Without. water we are nobody! Santos stated.
