Experts believe high water temperatures are the most likely cause of the deaths in the lakes in the region. Temperatures since last week have exceeded 39 degrees Celsius (102 degrees Fahrenheit) in the Tefe Lake region. There had been some 1,400 river dolphins in Tefe Lake, said Miriam Marmontel, a researcher from the Mamiraua Institute. Fleischmann said water temperatures rose from 32 C (89 F) on Friday to almost 38 C (100 F) on Sunday.
