Lake Erie Conditions Statement – Flood Outlook

Date: March 19th, 2020

For Thursday, March19th, 2020, this notice is intended to update the public and local municipalities of the condition of the Lake Erie Shoreline as it relates to the Niagara Peninsula and the eastern portions of Haldimand County.

Environment Canada has issued a Special Weather Statement calling for the possibility of thunderstorms with potential gusts of wind approaching 90km/hr.  These wind gusts could cause significant wave action and will cause water levels to increase along the Lake Erie Shoreline. Current forecasts are calling for sustained winds out of the southwest at 40 to 50km/hr. with the potential for gusts of up to 90km/hr.

As of March 18th, Lake Erie’s water level was sitting at 174.94m which is 86cm (34 inches) above average for this time of year.  The Ministry of Natural Resources and Forestry is currently predicting water levels to increase by 50cm (20 inches) above current levels to an elevation of approximately 175.33m.  Significant wave heights of 1.5m (5 feet) are also forecast to occur all along the Lake Erie shoreline from Haldimand County to Fort Erie. Peak water levels will occur early morning on Friday with a second peak around mid-afternoon.  Water levels will start to drop early evening Friday and into Saturday.

Stakeholders with interests along Lake Erie should pay close attention to water levels and waves in their area. Residents along the lakeshore are urged close storm shutters and stay away from the shoreline.

The NPCA will continue to monitor these conditions and will issue further messages as required. Information on the Flood Status in the watershed and water levels within the Great Lakes and streams can be found on the NPCA’s website at:




This notice is in effect until 9:00am, Saturday March 21st, 2020 and will be updated as required.

What if a Flood Message is Issued for Your Area?

Take heed of the message issued.

Be prepared to follow the advice and instructions of emergency response officials.

Monitoring weather and flood conditions is a shared responsibility of Conservation Authorities, OMNR, and Environment Canada. The OMNR Surface Water Monitoring Centre in Peterborough monitors weather forecasts and water levels across the province, providing the information to Conservation Authorities. Other information is also available from Environment Canada.

Conservation Authorities and the Ontario Ministry of Natural Resources are responsible for forecasting where and when flooding is likely to occur and issuing appropriate messages. Advance warning of an impending flood allows municipalities and other government agencies to put emergency response plans into operation, and if necessary, evacuate communities.

When flooding is possible or about to occur, Conservation Authorities (or the Ministry of Natural Resources in areas where there is no Conservation Authority) issue flood messages to municipal emergency management officials and the media. The municipal officials then take action to warn local residents. Flood messages are posted on Conservation Authorities’ websites. In some watersheds, members of the public can receive flood messages directly through e-mail and/or Twitter.
