Beach Conditions

Natural bodies of water are great places to play, swim and cool off on a hot sunny day.

However, swimming in these areas is not risk-free. There is always a level of risk when swimming in a natural water body, whether it's on the shores of Lake Erie, jumping off a dock at a cottage or going to a GRCA beach.

Natural water bodies, such as rivers and reservoirs, are exposed to contamination from various sources. The conditions and quality of the water can change quickly due to a number of environmental factors. These factors can influence the level of bacteria in the water to the point where it increases the risk of getting sick.

Environmental factors that can cause an increase in bacteria levels

• Recent heavy rainfall (1 to 2 inches or 25 to 50 mm within 24 to 48 hours) has a significant impact on water quality. Run off from the rain washes bacteria from the shore, fields and streets into streams, rivers and lakes.
• Cloudy water (unable to see feet in waist-deep water) means the sand and silt has been stirred up. This can increase the levels of bacteria in the water.
• High wind can cause waves, and wave action can stir up the sand and silt, which can increase the levels of bacteria in the water.
• Large numbers of birds or other wildlife and their droppings can have a significant impact on water quality. Dead fish, algae/scum, or debris in the water can also increase the risk of illness or injury.

How you can prevent illness when swimming in a natural water body

• Never swallow the beach water, at any time, no matter how clear!
• After swimming or playing in the water or sand, wash your hands or use a hand sanitizer, and always before eating, especially for children. Bacteria levels tend to be higher in the warm wet sand on the shore.
• Parasites that can cause illness and skin irritation live in natural water bodies. Make sure you shower or towel dry after you exit the water.

Help keep our beaches clean

There are a number of ways you can help keep our beaches clean and improve water quality conditions in our swimming areas. These include:

• Don't feed wildlife or birds.
• Don't use soaps, shampoos, or other bathing products in the water.
• Use appropriate washroom facilities.
• Place all garbage in designated bins, or take it with you.

Beach Closures

A beach closure (rarely issued) would prohibit swimming due to various reasons, for example, a chemical or sewage spill.
