Flood Status

WATERSHED CONDITIONS STATEMENT – Flood Outlook

Date: July 28, 2017

This notice is intended to update the public and local municipalities of the condition of Lake Ontario as it relates to the Niagara Peninsula and the eastern portion of the City of Hamilton.

The record high water levels of Lake Ontario have decreased and are currently at 75.64m. This is 24cm lower than the peak water level reached on May 29th.  Lake Ontario water levels have remained high but are slowly declining as summer progresses.

The current forecast is calling for strong north-east winds starting this morning. During this time, there is an increased risk of backshore flooding, shoreline flooding and shoreline erosion resulting from storm surge and increased wave action. Wave heights may exceed 0.5m further exacerbating the current high lake levels.

Residents living along Lake Ontario from Hamilton to Niagara-on-the-Lake are urged to exercise caution near the lakefront and to monitor meteorological conditions, paying particular attention to wind direction and speed.

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 streams can be found on the NPCA’s website at:

This notice is in effect until noon, Sunday, July 30, 2017, 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.
