RVCA's Role

RVCA 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 adviceso 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.
