It’s that time of year again; be on the lookout for blue-green algae blooms. The Water Security Agency says people should stay out of the water and avoid drinking water where the blooms are occurring. They commonly occur during calm, hot weather in lakes and reservoirs with shallow, slow-moving or still water that has sufficient nutrients. Pets and livestock should be kept clear of such water as well.
The blooms often give the water a shimmering, foamy, pea soup appearance. They can be blue-green, bright blue, grey, or tan coloured. The blooms typically last for up to three weeks and can be pushed around by the wind.
Coming in contact with contaminated water can cause red skin, sore throat, cramps, or diarrhea. You should also be cautious about eating fish or shell fish caught in these bodies of water. If you have symptoms you are urged to call the 8-1-1 Healthline or your health care provider.
