What do the results mean?

  • GREEN: The water is safe for swimming. Have fun!

  • RED: Swimming is not recommended. High bacteria levels may cause minor infections or stomach issues.

  • CLOSED: The beach is temporarily unsafe due to health risks like chemical spills or sewage contamination.

  • BLANK: No sample is currently available.

Tip: Weather can change water quality quickly. Heavy rain or strong winds may increase bacteria levels, even if the results are green.

When is beach water tested?

Our Environmental Health team tests water weekly from June 10 to Labour Day weekend.

  • Samples are collected on Mondays or Tuesdays after holidays

  • Results are posted within 24-48 hours, so you can plan ahead

What impacts water quality?

Water quality can change based on the weather and environment. Common factors include:

  • Rain runoff: Stormwater carries bacteria and pollution into the lake.

  • Bird droppings: Ducks, geese, and seagulls are frequent contributors to bacteria.

  • Warm temperatures: Bacteria grow faster in hot water.

  • Other risks: Debris, algae blooms, or spills may also make water unsafe.

Tip: Avoid swimming for 48 hours after heavy rain or strong winds to reduce your risk of exposure to harmful bacteria.

Why do we test beach water?

We test for E. coli bacteria to make sure swimming is safe. High levels of E. coli can cause:

  • Stomach upset (e.g., diarrhea, nausea)

  • Skin irritations or infections

  • Eye, ear, nose, or throat problems

Testing helps keep you and your loved ones safe while you enjoy the water.

How can you stay safe at the beach?

A few simple precautions can make your beach day safer:

  • Don’t swallow lake water

  • Shower after swimming

  • Avoid swimming if you have cuts, open wounds, or aren’t feeling well

  • Stay out of the water if it looks murky or unclear

Remember: Check conditions before swimming and avoid the lake after heavy rain or wind.

Frequently asked questions

  • RED: Swimming is not recommended, but you can still visit the beach. If you choose to swim, avoid dunking your head or swallowing water.
  • CLOSED: The beach is unsafe for any activity. Stay out of the water until it reopens.

At least 48 hours (two days). Water can change day-to-day or even hour-by-hour. Rain, wind, or heat may raise bacteria levels before new tests are completed. Please consider recent weather conditions when deciding on whether or not to go swimming.

  • Don’t feed birds at the beach

  • Always clean up after pets

  • Dispose of trash properly
