This notice is intended to update the public and local municipalities of the condition of watercourses as it relates to the Niagara Peninsula and the eastern portion of Hamilton and Haldimand County.


A low-pressure system associated with the remnants of Hurricane Gordon is tracking close to the Niagara Peninsula. At this time the Niagara Region and Haldimand County are under a Rainfall Warning as issued by Environment Canada.  The forecast is calling for approximately 50mm of rain to fall, possibly heavy at times.  The rain will start late this evening and should start to taper off tomorrow afternoon.  The heaviest rains will fall through the overnight hours.


Water levels in local creeks and rivers are currently well below critical thresholds and the NPCA does not expect any major flooding associated with this event.  However, localized flooding of low-lying areas prone to flooding is possible.  


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 local watercourses can be found on the NPCA’s website at:





This notice is in effect until noon Tuesday September 11th, 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.

Flood Messages are shown on this site appear as a message in the bar under the navigation.
