Weather data
We maintain an important flood forecasting and warning system that monitors river and weather conditions 24-hours a day, 365 days a year.
Weather forecasts are monitored regularly to detect conditions that could cause flooding in the Grand River watershed.
Gauges and monitoring stations are located throughout the watershed that provide real-time information on weather and river flow conditions.
These stations include:
- 24 rainfall stations,
- 4 total precipitation stations, measuring snow, rain and mixed precipitation
- 15 air temperature stations
We also monitor barometric pressure, snow depth, and wind speed which help with decision-making around flood and reservoir operations.
