Riverine Flood Watch (Event Message #3)

The Long Point Region Conservation Authority is updating the Flood Watch for its entire watershed. The Flood Warning for Big Otter Creek has been downgraded to a Flood Watch.

The watershed received 15-20 mm of rain yesterday. This, combined with the melting snowpack, significantly raised water levels and moved ice in local watercourses. With the rapid drop in air temperatures overnight, the rate of snowmelt and runoff decreased abruptly. Much of the water and snow remains in the fields this morning. Stream flows in the Big Otter have crested just below flood levels and are beginning to recede. Stream flows in Big Creek crested in Delhi overnight and may continue to rise moderately in lower Big Creek today. Flood Coordinators are encouraged to continue monitoring river conditions throughout the day.

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 Flood Watch 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 Watch: A message issued by the Conservation Authority to advise flooding is possible in specific watercourses or municipalities. Municipal flood coordinators, emergency services and individual landowners in flood prone areas should prepare.
