Flood Forecasting and Warning System

One of the most important responsibilities of Conservation Authorities is to protect people and property from flooding. Information gathered from our system of streamflow gauges, snow courses and weather stations allows us to prepare water level and flow forecasts which are used to warn watershed residents of potential flooding.

See our Flood Resources for additional information from other reputable sites.
