FLOOD WATCH
Date: June 14, 2026, 2026 The Niagara Peninsula Conservation Authority (NPCA) is advising the public and local municipalities of the potential for flooding within its jurisdiction on Sunday, June 14, 2026. This includes the Niagara Peninsula, the southeastern portion of the City of Hamilton, and the eastern portion of Haldimand County.
The Niagara Peninsula Watershed is currently under a Severe Thunderstorm Watch, with forecasted rainfall totals of 30–50 mm. The watershed has already received 10–30 mm of rain in a short period, with the northern areas experiencing the highest amounts. Current forecasts indicate an additional 25–50 mm of precipitation is possible.
Smaller watercourses are expected to respond rapidly to these rainfall amounts. While the NPCA does not anticipate major flooding along larger watercourses, nuisance flooding in low-lying areas adjacent to smaller streams and creeks is likely.
Residents are strongly urged to stay clear of all creeks, rivers, and waterbodies due to slippery banks and elevated water levels, which pose significant hazards. Property owners are encouraged to ensure that drainage features—such as culverts, catch basins, and ditches—are free of debris. Municipal and Regional staff are similarly advised to inspect and clear local stormwater infrastructure.
This notice remains in effect until 12:00 PM on Monday, June 15, 2026, and will be updated as conditions warrant.
The NPCA will continue to monitor these conditions and will issue further messages as required. Information on the Flood Status in the watershed can be found on the NPCA’s website at:

How Flood Warnings Work
Conservation Authorities and OMNR:

- Activate emergency plans
- Warn residents
- Evacuate areas if necessary
- Municipal emergency officials
- Media outlets
- Public alert platforms like Alertable
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.
