FOR IMMEDIATE RELEASE

September 6th, 2019

This notice is intended to update the public and local municipalities of the status of Lake Erie and Lake Ontario conditions within the Niagara Peninsula and the eastern portions of the City of Hamilton and Haldimand County.

LAKE ERIE

Currently Lake Erie water levels are continuing their slow decline but remain at record levels for this time of year. As of September 4th, Lake Erie’s static water level was 174.92m. This water level is 70cm above average and 6cm above the record-high set during this week back in September of 1986. This level does not account for any increase in water levels due to storm surge or wind driven waves. Stakeholders with interests along Lake Erie should pay close attention to any weather systems that generate strong sustained West to Southwest winds as the resulting storm surge could result in shoreline erosion due to damaging waves and localized flooding.

LAKE ONTARIO

Currently Lake Ontario’s water level is continuing to decline. As of September 4th, the static water level was 75.35m which is 53cm above average and 57cm below the peak level of 75.92m recorded on June 15th, 2019. These static water levels do not account for storm surge and wind driven waves. Stakeholders with interests along Lake Ontario shoreline should pay close attention to weather systems that bring sustained winds from the East and Northeast as the resulting storm surge could result in erosion due to damaging waves and localized flooding.

Water levels on both Lakes will continue their slow decline but will remain above average into the winter months. The NPCA is monitoring the situation closely and will provide updates 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.
