SHA warns of possible toxic algae at Buffalo Narrows

Jul 28, 2026 | 5:02 PM

The Saskatchewan Health Authority (SHA) is warning the public that toxic algae may be present at all swimming locations around Buffalo Narrows.

According to the Water Security Agency, blue-green algae are naturally occurring bacteria that can be present in water bodies, particularly lakes and reservoirs. The blooms can last up to three weeks and can be pushed around the lake or reservoir by the wind.

Many of Saskatchewan’s southern lakes are prone to blue-green algae, but it can occur in Northern Saskatchewan if the weather and conditions are just right.

Toxic algae will appear as surface scum with shimmering, foamy or pea soup like appearances. Often blue-green in colour, these algae can also form blooms that are bright blue, grey, or tan in appearance. Blue-green algal blooms commonly occur during calm, hot weather in areas of lakes and reservoirs with shallow, slow moving or still water that has sufficient nutrients.

If you notice these signs, avoid direct contact with water where algae blooms are occurring. If contact occurs, wash with tap water as soon as possible.

Do not swim or allow your pets to swim in the area, do not feed whole fish or fish trimmings from the lake to your pets, and limit or eliminate human consumption of fish organs or shellfish caught in the lake. Direct contact or unintended consumption of algae-contaminated water can cause red skin, sore throat, cramps, nausea, vomiting and diarrhea.

The SHA is advising the public to contact a doctor or veterinarian if you or your animals have sudden or unexplained sickness or signs of poisoning.
