What is stormwater?
Stormwater is rain or melted snow that flows over hard surfaces like roads, driveways and roofs. It runs into drains and then into creeks, ponds and wetlands.
Unlike sewage, stormwater isn’t treated before it enters waterways.
How the city manages stormwater
We use a network of ponds, drains, pipes and green spaces to collect and manage stormwater safely.
This helps:
- prevent flooding during heavy rain
- protect homes, roads and trails
- reduce pollution entering local waterways
Monitoring water quality and flow
We monitor local creeks and ponds to track water quality, flow and rainfall. The GRCA also monitors surface and groundwater across the watershed. Learn more on the GRCA Surface Water Monitoring page.
Stormwater ponds and safety
Stormwater ponds collect runoff and help control flooding and erosion. They also capture pollutants before water reaches local creeks and rivers.
These ponds are not safe for recreation. Ice can break without warning.
Learn how to stay safe around stormwater ponds.
Manage flooding and drainage
Pooling water after rain or snowmelt can often be fixed through grading or drainage improvements.
Learn how to manage grading and drainage on your property.
Help protect our stormwater system
Everything that enters a storm drain flows directly into local creeks and rivers. Help keep pollution out of the system.

Keep storm drains clear
Catch basins, the grates at the edge of streets, collect rainwater and direct it into the city’s stormwater system. Help prevent flooding by keeping nearby drains clear of trash and leaves.
