A Calgary man is dead after the Bow River swept him downstream near Canmore.
Canmore RCMP say the 63-year-old man was swimming with friends near the Seebe Dam, located west of Calgary.
As he came out of the water, he fell back in and drifted downstream.
"He was located by friends and attempts were made to revive him," police said in a statement.
"Due to the remoteness of the location, he and his friends were extricated by helicopter and were met by paramedics who were unsuccessful at reviving him."
Back-to-back rescues in Calgary
In Calgary, crews had to perform back-to-back water rescues on the Bow River Sunday evening, prompting the fire department to remind Calgarians to use common sense.
The aquatics rescue team was on a routine patrol when two people were spotted clinging to a safety boom upstream of the rapids at Harvie Passage, south of the zoo.
Rescuers brought the pair to shore safely. One woman was not wearing a life vest, officials said.
The June floods caused extensive damage to the passage and have made it too dangerous to use, officials said on the weekend as the temporary safety boom was installed. Rafters should leave the river upstream of Harvie Passage until repairs are complete, officials said.
"The water is very cold and people will lose their strength rapidly," the fire department said in a release. "Had the boom not been in place the two would likely have gone over the falls within the passage."
Putting first responders at risk, says official
Minutes later crews were called back upstream where a man was stranded on a bridge abutment at 10th Street N.W., having been thrown from his raft.
Crews lowered a life jacket down to the man from the bridge as a member of the dive team swam out to him.
The rescue boat then picked them up.
"It's not a safe situation and we're putting our own people at risk trying to deal with these individuals," said Battalion Chief Ernie Molineaux.
