This is the best summary I could come up with:

More than a hundred dolphins have been found dead in the Brazilian Amazon amid an historic drought and record-high water temperatures that in places have exceeded 102 degrees Fahrenheit.

The dead dolphins were all found in Lake Tefé over the past seven days, according to the Mamirauá Institute, a research facility funded by the Brazilian Ministry of Science.

The institute said such a high number of deaths was unusual and suggested record-high lake temperatures and an historic drought in the Amazon may have been the cause.

Researchers and activists are trying to rescue surviving dolphins by transferring them from lagoons and ponds in the outskirts to the main body of the river where the water is cooler, reported CNN Brasil, but the operation is not easy due to the remoteness of the area.

Below average levels of water have been reported in 59 municipalities in Amazonas State, impeding both transport and fishing activities on the river.

Authorities expect even more acute droughts over the next couple of weeks, which could result in further deaths of dolphins, CNN Brasil reported.
