Neighbourhood ponds

Suburbs

Ponds often add to the aesthetic appeal of a neighbourhood. But, a pond's real purpose goes beyond appearance. They're a key component of our stormwater management program.

Stormwater management ponds collect rainwater, which has travelled across nearby streets and parking lots, picking up oil, grit and road salt along the way, and filter out pollutants before they make their way to our creeks, rivers and lakes.

Though our ponds are designed to be cleaned out every seven to 10 years, we regularly inspect them to make sure they're in good condition and working properly.

Pond types

Depending on the neighbourhood, a specific type of pond may be built to limit the amount of rainwater from entering our watercourses. Here are the most common examples:

  • Wet pond: This type of pond has a permanent pool of water. The design allows for sediment to settle and collect at the bottom - separating and cleaning the water. Once clean, the water is slowly released through an outlet pipe into a nearby watercourse.
  • Wetland: This type of pond often has water, yet tends to be marshy and shallow. Sediment settles to the bottom and special plants are used to help filter the water. Once clean, the water is slowly released into a nearby watercourse.
  • Dry pond: This type of pond doesn't typically have water, unless there is a large rain storm. During a rain event, the pond fills with water that's slowly released into the receiving watercourse, but sediment does not settle or collect. Once the rain event is over, the remaining water either absorbs into the ground or evaporates.

Pond precautions

With the growing number of homes in our city, neighbourhood ponds have become more commonplace.

This presents safety risks to anyone who chooses to go near them, as the ground, as well as winter ice around a pond can be unpredictable and dangerous; and unsafe amounts of bacteria and contamination can make the water unsafe.

For your safety, please refrain from going too close to our local ponds, or playing around them.

Do your part - help a stormwater management pond do its job!

  • Avoid using driveway paving chemicals or fertilizers on your property. These untreated chemicals flow to our stormwater management ponds and end up in our creeks and rivers.
  • Do not release goldfish or any other non-native, invasive species into our stormwater management ponds or other natural bodies of water. These fish species multiply at a rapid pace, pushing out the native fish habitat. They also disturb the sediment at the bottom of a pond - often causing the sediment to enter into our creeks and rivers.
  • Collect rainwater on your own property and apply for a stormwater credit. This is a great way to save water and money!
  • Take advantage of our local outdoor rinks. They are maintained by volunteers and offer a great alternative to creating a rink on a stormwater pond.
