Flood Warning & Forecasting
Subscribe to receive CLOCA Flood Messages.
Central Lake Ontario Conservation (CLOCA) monitors, on an ongoing basis, weather forecasts and watershed conditions at locations across the watershed.
Our Water Monitoring Network is a collection of stream gauges, rain gauges, air and water temperature probes, groundwater monitoring wells, snow measurement sites, surface water and groundwater quality sampling sites. These measurements, weather forecasts and radar information on temperatures and rainfall predictions, along with historic data, are all taken into consideration when developing a flood forecast.
The data is catalogued and analyzed to develop effective watershed wide management programs in support of our polices like the Flood Forecasting and Warning System, Low Water Response and Source Water Protection programs. Observing trends over time requires long term tracking and monitoring.
