The carcasses of 120 river dolphins have been found floating in a tributary of the Amazon River over the last week in circumstances that experts suspect were caused by severe drought and heat. Low river levels during a severe drought have heated water in stretches to temperatures that are intolerable for the dolphins, researchers believe. Thousands of fish have died recently on Amazon rivers due to a lack of oxygen in the water.
Low river levels in Calgary spark concerns
Despite recent rainfall over Calgary, conditions are still drier than usual, leading to concerns over low water flows in the region. "The flows in both the Bow and Elbow Rivers continue to be well below normal for this time of year due to the low snowpacks and early snowmelt in the Bow and Elbow River Basins, as well as ongoing dry conditions," the City of Calgary said in a statement Friday. "Reservoirs upstream of Calgary are currently filling and the Glenmore Reservoir is being held at full supply level to proactively manage water supply in anticipation of a hot, dry summer."

A summer of 'desperate' low river levels in central Newfoundland could have lasting impacts: scientist
When Craig Purchase visited his normal fishing spot upstream of Terra Nova Lake this past Labour Day weekend, it was clear why angling was off the table. "Where it would normally be waist deep, there was two to three inches of water," Purchase, who's also a professor of biology at Memorial University, said. Bare rocks and trickling brooks have been a common sight through a swath of central Newfoundland this summer, Purchase said.
