Riverine Flood Watch and Warning (Event Message #2)

The Long Point Region Conservation Authority is updating the Flood Watch for its entire watershed and upgrading the Flood Watch to a Flood Warning for Big Otter Creek in Bayham Township.

The watershed has received 15-20 mm of rain over the past 24 hours. The rain, in combination with the melting snowpack, has created significant runoff. Water levels in local watercourses are rising rapidly and will continue to rise over the next 24 hours.

ACTION: The flows in Big Otter Creek at Tillsonburg and Calton have not yet crested. If flows continue to increase at the current rate, minor flooding may occur in areas along the lower Big Otter Creek in Bayham Township, specifically in the town of Vienna. Flood coordinators should closely monitor river conditions and warn property owners in the most flood-prone areas of Vienna about the potential for flooding.

People are warned 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 advised to ensure that dams, culverts, and catch basins are free from debris and functioning properly, if the work can be done safely.

This Combination Flood Watch and Flood Warning will remain in effect until 4:30 PM, Friday, March 7, 2025. LPRCA staff will continue to monitor 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: Flood Warning – Flooding is imminent or already occurring in specific watercourses or municipalities.
