Flood Watch (Event Message #2)

The Long Point Region Conservation Authority is updating the Watershed Conditions Statement—Flood Outlook to Flood Watch for the entire watershed. Residents near creeks and streams are urged to stay informed with the latest weather updates and exercise caution, particularly in areas prone to flooding.

Over the last 24 hours, the Long Point Region watershed received approximately 44 mm rain, causing creek flows to rise significantly. The riverine water levels and flows have already increased, and the rate of increase is expected to continue until they crest. Big Otter Creek flows through Vienna are currently expected to stay within the banks but are likely to resemble the high flows seen earlier in March (March 5, 2025).

Another 30-35 mm of rain is forecast to begin late tomorrow, Friday, April 4th, and continue into Saturday, April 5th. This combination of factors may overwhelm watercourses, leading to localized flooding in low-lying areas.

People are advised to stay away from ditches, water bodies, streams, rivers, and ponds, as the combination of slippery banks and 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 Riverine Flood Watch will remain in effect until 4:30 PM on Monday, March 7, 2025. LPRCA staff will continue to monitor the forecasted conditions and will update this message as necessary.

Contact Paul Gagnon, Lands & Waters Supervisor at lprca.floodmessage@lprca.on.ca or 519-429-4899 should further information be required.

Note: Flood Watch: Flooding is possible in specific watercourses or municipalities. Municipal flood coordinators, emergency services, and landowners in flood prone areas should prepare.
