Effective advisories and warnings help minimize flood risks
Accurate flood forecasting and an effective warning system can minimize the risk to human life and property damage that can result from flooding.
Snow melt and rainfall can cause serious flooding and damage to property, shorelines and other structures. Forecasting possible flooding, and warning watershed residents are key responsibilities of Mississippi Valley Conservation Authority (MVCA).
MVCA monitors weather information, river flows, snow pack and ice conditions to predict when flooding could occur and how high the water may rise.聽When flooding is possible, MVCA issues a flood message based on conditions to municipal emergency management officials and the media with messaging that is聽consistent across the Province.
MVCA advises watershed municipalities about potential conditions for flooding within the watershed. Updated flood advisories or flood warnings are prepared as conditions warrant.
How We Forecast
In order to forecast potential flood events MVCA staff continuously monitor the water conditions across the watershed especially stream flows and lake levels.
This is done through:
- extensive network of automated recorders (stream gauges) and human observation (staff gauges)
- measuring snow water content and density (snow courses)
- monitoring temperature and precipitation forecasts
These measurements, weather forecasts and radar information on temperature and rainfall predictions, along with historical data, are taken into consideration when developing a flood forecast.聽
