What are stormwater ponds?
There are three types of ponds that can collect water and each serve a different function.
Dry Pond - This pond is dry 90 per cent of the time and can contain playing fields. They fill with water during heavy rains and can take up to 24 hours to drain once the rain stops.
Wet Pond - A wet pond captures and contains stormwater – for a while. Wet ponds slow down water long enough to settle out sediments and pollutants. They help return cleaner water to our rivers and streams. They are a critical piece of infrastructure.
Wetland - A natural marsh or a bog; it contains plants and the water is quite shallow before a storm. The plants that grow in the wetlands help filter out the fertilizers and pesticides that some people put on their lawns.
Why are stormwater ponds important?
- Holds excess rainfall to prevent flooding
- Helps to settle out sediment and other contaminants before being released downstream into creeks and rivers
- Creates habitat for wildlife
- Creates a park-like setting
How can I help improve the water that goes into stormwater ponds?
- Reduce the risk. Harmful substances can find their way into the ponds. Risks include excess herbicide on your lawn or gasoline spilling from your lawnmower.
- Point downspouts toward lawns and gardens or use a rain barrel.
- Limit the use of fertilizers and pesticides.
- Sweep up debris from your garage and driveway instead of washing it away.
- Wash your vehicle at a car wash instead of your driveway.
- Clean up after your pet.
