Water Quality Monitoring – Blue-Green Algae (Cyanobacteria)

Before enjoying the beach, take a moment to check the current water quality. The presence of cyanobacteria (commonly known as blue-green algae) can pose health risks to both humans and animals.

📍 Higher-Risk Areas

While campground beaches are generally sheltered from blooms, blue-green algae are more frequently observed near the municipal dock and Jameson Park, due to wind and water movement. Stay alert and avoid swimming if visual signs of contamination are present.

🧠 About Cyanobacteria

Cyanobacteria are microorganisms that occur naturally in lakes. During hot weather, they can multiply quickly and form visible surface scum or greenish patches in the water.

Some species may produce toxins harmful to human and animal health.

⚠️ Safety Tips for Water Activities

Before entering the water:

• Check the water’s appearance:

  • Green water, surface scum, or foam may indicate cyanobacteria – avoid contact and keep pets away.

  • An oily sheen may suggest petroleum contamination.

  • After heavy rain, wait at least 24 hours before engaging in water activities: runoff can carry fecal or other pollutants.

During water activities:

• Avoid swallowing water.

• Do not swim with open wounds.

• Towel off thoroughly after leaving the water.

• Wash your hands before eating.

• Take a shower as soon as possible after water activities.

🚑 Possible Health Effects

If you swallow contaminated water:

Risk of gastroenteritis – symptoms may include vomiting, diarrhea, abdominal cramps, and fever. These can be more severe in young children or vulnerable individuals.

If your skin comes into contact with contaminated water:

Risk of rash, redness, eye or ear irritation, or infections in existing wounds.

If you develop symptoms after water activities, call Info-Santé at 811, or consult your pharmacist or health professional.
