A Flood Watch Report from the Niagara Peninsula Peninsula Conservation Authority (NPCA)
Posted April 2nd, 2025 on Niagara At Large
Niagara, Ontario – For Wednesday, April 2nd, 2025, this notice is intended to advise the public and local municipalities of the potential for flooding within the NPCA’s jurisdiction as it relates to the Niagara Peninsula, the southeastern portion of the City of Hamilton and the eastern portion of Haldimand County.
Environment and Climate Change Canada has issued a rainfall warning for Southern Ontario. A low-pressure system is forecasted to move into the province on Wednesday morning, bringing rain and freezing rain to much of Southern Ontario.
Rainfall amounts of 30 – 50 mm are expected to begin Wednesday morning into Thursday morning with potentially higher amounts in localized areas due to thunderstorms. Another 30 – 50 mm of rain is forecasted to fall over the weekend, which may increase the risk of flooding of local watercourses as they work to drain the runoff from the previous event.
At the present time, water levels in the local watercourses are at or slightly above the seasonal average but remain well below critical flood elevations. This rain will serve to further increase water levels in our local creeks and rivers and will likely result in flooding typically experienced in low-lying, flood prone areas. Major flooding of watercourses is not anticipated at this time.
Residents are urged to stay away from creeks, rivers and all waterbodies at this time due to slippery slopes and elevated water levels as they can be hazardous. We also encourage residents to ensure drainage on their property is not hindered by blocked culverts, catch basins or ditches. Municipal and Regional staff are also reminded to check local storm sewer infrastructure to ensure its capabilities for this event.
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: https://npca.ca/flood-status

This notice is in effect until 9:00 AM, Monday, April 7th, 2025, and will be updated as required.
A Brief Footnote from Doug Draper At Niagara At Large – If you are living in a front-prone area, and even if you are not, and you have a home with a basement in it, you might want to temporarily remove anything of value off the floor. You might want to role up any rugs you have on your basement floors too. Take it from a homeowner who has had too much experience with basement flooding.
