River Gauges

River gauges measure important information such as flow, which is how much water is moving through the river at a given point, measured in cubic metres per second (m³/s). Higher numbers mean more water and faster current. The gauges below are monitoring stations along the Thames River watershed that report data to Environment Canada throughout the day.

As a paddler, flow tells you whether conditions are right for being on the water. Too low and you'll be scraping bottom, walking your kayak along the river more than paddling it. Too high and the river moves fast, hazards are harder to spot, and capsizing has serious consequences. Each section of the river has a suggested flow range where paddling is comfortable, safe, and enjoyable.

The colours match the homepage: green means flow is in the good range, yellow means it's borderline, and red means stay off the water. The charts show how flow has been trending. A rising line after rain means conditions could worsen, while a falling line means they're improving.
