The Northwestern Health Unit is advising the public to be alert for blue-green algae blooms.
The blooms are blue-green and may cover the water with a florescent paint-like scum.
Fresh blooms smell like freshly cut grass while older blooms smell like rotting garbage.
Public Health Inspector Brian Norris says there can be health effects associated with them.
"Human health effects from contact with these toxins may include itching, irritated eyes and skin," says Norris. "If the toxins are swallowed, symptoms such as headaches, fever, diarrhea, abdominal pain, nausea and vomiting may occur."
If you experience any of these symptoms contact your physician.
