Watershed Conditions Statement - Flood Outlook *UPDATE*
Date: April 2nd, 2026 The Niagara Peninsula Conservation Authority (NPCA) is advising residents, businesses, and local municipalities of a potential risk of flooding across the Niagara Peninsula, including portions of southeastern Hamilton and eastern Haldimand County.
Over the past four days, the watershed has received approximately 15 to 50 mm of rainfall, with the southern Niagara Peninsula experiencing the highest amounts. This rainfall has resulted in increased water levels and flows in local creeks and rivers.
Additional rainfall is forecast through the weekend, with an additional 20 to 30 mm expected. Light rain is forecast to begin this afternoon and taper off Friday afternoon, with another round of rainfall expected on Saturday. The heaviest rainfall is anticipated Saturday night.
The combination of ongoing rainfall, elevated water levels, and saturated ground conditions may cause further increases in water levels and could lead to localized flooding, particularly during periods of heavy rainfall. Rapid runoff into ditches, creeks, rivers, and storm sewer systems is possible.
At this time, creeks and rivers remain below critical flood levels, and major or widespread flooding is not anticipated. However, additional rainfall could result in minor flooding in low‑lying and flood‑prone areas.
Residents are urged to use caution and stay away from rivers, creeks, and other waterbodies, as fast‑flowing water and slippery banks can be dangerous. Property owners are encouraged to ensure that culverts, catch basins, and roadside ditches on or near their properties are clear of debris. Municipal and regional staff are also encouraged to confirm that storm sewer systems are functioning properly ahead of the forecasted rainfall.
This notice is in effect until 9:00 AM, Tuesday, April 7th, 2026, and will be updated as required.
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:

What To Do If a Flood Message Is Issued
- Read the alert carefully.
- Follow instructions from emergency officials.
- Be prepared to act quickly, including evacuating if required.
Who Monitors Flooding?
Weather and water levels are monitored by:
- Conservation Authorities
- Ontario Ministry of Natural Resources (OMNR)
- Environment and Climate Change Canada
- The OMNR Surface Water Monitoring Centre tracks conditions across Ontario and shares information with Conservation Authorities.
How Flood Warnings Work
Conservation Authorities and OMNR:
- Predict where and when flooding may occur
- Issue flood warnings and advisories
- 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.
