While not fatal to humans, public safety is cautioning people to stay away from any water sources where blooms might be present.

Dog owners being warned of blue-green algae toxicity after a number of pets fall ill around Lake Winnipeg.

"Some types of blue-green algae produce toxins during blooms, and when these blooms decay, the toxins may be released into the water, posing a risk to people and pets."

The dogs died just a few hours after swimming in a pond filled with blue-green algae, which can produce a powerful toxin.

Swimmers should take note that Alberta Health Services has multiple water quality advisories in effect for areas in central and northern Alberta.
