Flood Forecasting & Warning

Lower Trent Conservation maintains a flood forecasting and warning system to provide early warning of possible risks to people and property from flooding.  We provide local municipalities, other agencies and the public with advance notice, information and advice so that they can respond to potential flooding and flood-related emergencies.

We use stream gauges, weather stations, snowpack measurements, weather forecasts and computer models to determine the potential for flooding. When spring melt or severe storms are anticipated, Lower Trent Conservation estimates the severity, location, and timing of possible flooding.

Our Flood Contingency Plan outlines our roles and responsibilities as well as those of local municipalities and the Province.
