There have been several drownings in Alberta this year and officials say the most dangerous time of summer for water-related deaths is still to come.

Statistically the next 30 days are the worst time of year for drownings, and males aged 15 to 35 make up the bulk of them.

Barbara Costache, an Alberta spokesperson for the Lifesaving Society, says young men like to take risks.

"They have this sense I'm invincible," she said.

Costache says there is another male age demographic whose members are also at greater risk for drowning, and this is a group of people who should know better — aging baby boomers.

"Our baby boomer drownings are going up and they've been going up over the last six years or so. And that's largely due to our baby boomers are still recreating and they're still demonstrating the same risky behaviours," she said.

"They still haven't learned to wear their life jackets, to not drink and boat. To not go out and be on the water alone."

Last year 22 people drowned in Alberta — 16 of those fatalities were men.

The Calgary Fire Department has been warning residents for some time that the Bow River remains dangerous after last year's floods.

​​“The river advisory that was put into effect after last year's flood has not been lifted," said spokesperon Carol Henke in April.

"And that is because there are still many hazards in and around the river that you can and cannot see that create significant danger to river users.”
