WATERSHED CONDITIONS STATEMENT – Flood Outlook

Date: November 20th, 2018

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 portion of Haldimand County.

Winds will build throughout the night and will peak Wednesday morning. Winds will be 40km/hr gusting to 70km/hr and will begin to diminish and shift direction Wednesday morning. The direction and speed of the wind will increase water levels in the Eastern Lake Erie Basin.

The Ministry of Natural Resources and Forestry (MNRF) are forecasting Lake Erie water levels at Port Colborne to increase due to surge by 0.6m over current water levels with significant wave heights up to 2.0m. Peak water levels are forecasted to occur early Wednesday morning. During this time, there is an increased risk of shoreline erosion and flooding resulting from strong wave action and surge. Residents living along Lake Erie are urged to monitor the situation closely.

Please note that Lake Erie static (calm and flat) water levels are well above the long-term historical average and are forecasted to remain elevated through spring 2019. The potential for shoreline flooding and erosion is greater at this time due to the higher than normal Lake Erie water levels. Any moderate increase in West or Southwest winds will further increase this risk.

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 Thursday, November 21st, 2018 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.
