Flood Condition Index

Conditions are within NORMAL limits. No flooding is expected.

Watershed Condition Bulletins — contain information about current conditions in the watershed that set the stage for the possibility of flooding (if the right weather patterns should develop). “Be informed and aware.”

Flood Advisories — when it is perceived that flooding could result from an approaching weather system which is expected to bring heavy rain or warm air causing a rapid snowmelt. “Be prepared to activate your flood response plans, if it becomes necessary.”

Flood Warnings — when it is perceived that flooding conditions definitely will be experienced. “Activate your flood response procedures now.”

The RVCA's Role in Flood Forecasting and Warning

The Rideau Valley Conservation Authority maintains a flood forecasting and warning system. Our goal is to reduce danger to people and property by providing local agencies and the public with advanced notice, information and advice so that they can respond to potential flooding and flood emergencies.

The RVCA uses stream gauges, weather stations, surveys of snow conditions, meterological forecasts and computer models to determine the potential for flooding.

When spring melt or severe storms are anticipated, the Conservation Authority estimates the severity, location, and timing of possible flooding.
