Watershed Conditions Statement – Flood Outlook (Event Message #1)

The Long Point Region Conservation Authority (LPRCA) is issuing a Watershed Conditions Statement—Flood Outlook for its entire watershed, urging people near creeks and streams to stay aware of changing weather conditions, watch for localised flooding, and be prepared if flooding becomes more likely.

A Special Weather Statement is in effect from Wednesday, April 2, 11:00 AM EDT until Thursday, April 3, 10:00 AM EDT, predicting significant rainfall amounts of 30 to 50 mm, with locally higher amounts possible in thunderstorms. Rain is expected to begin Wednesday morning over extreme southwestern Ontario before reaching the Golden Horseshoe Wednesday afternoon. With thunderstorms particularly expected in some areas of southwestern Ontario, rainfall amounts may exceed 50 mm in the Long Point Region watershed. The rain will end from west to east Wednesday night into Thursday morning.

Under the forecasted conditions, riverine water levels and flows are expected to increase in the Long Point Region watershed. At this time, no major flooding is anticipated; however, some watercourses may reach or exceed their banks, creating localized flooding in floodplains, low-lying areas, and regions with poor drainage.

People are advised to stay away from ditches, water bodies, streams, rivers, and ponds, as the combination of slippery banks and cold fast-flowing water is dangerous. Landowners are also urged to ensure that dams, culverts, and catch basins are free of debris and functioning properly, provided the work can be done safely.

This Watershed Conditions Statement—Flood Outlook will remain in effect until 4:30 PM on Friday, April 4, 2025. LPRCA staff will continue to monitor the forecasted conditions and will update this message as necessary.

Contact Saifur Rahman, Manager of Engineering and Infrastructure at lprca.floodmessage@lprca.on.ca or 519.842.4242, ext.265 should further information be required.

Note: Watershed Conditions Statement – Flood Outlook: Early notice of the potential for flooding based on weather forecasts calling for heavy rain, snowmelt, high wind or other conditions that could lead to high runoff, cause ice jams, a rise in Lake Erie, lakeshore flooding or erosion.
