The latest update from the Ottawa River Regulation Planning Board indicates that water levels along the Ottawa River remain elevated due to ongoing spring runoff.

  • Water levels in the Pembroke / Lac Coulonge reach, including L’Isle-aux-Allumettes, are near their seasonal peak and show signs of stabilization or gradual decline under current conditions.
  • The forecast for the next few days indicates that levels will remain below the 2023 peak and well below the 2019 peak.
  • Minor flooding remains possible in low-lying areas, particularly along shorelines and flood-prone zones.

What this means locally

  • Some areas may continue to experience water pooling or minor flooding, especially in low-lying locations.
  • Some private roads remain closed.
  • At this time, there is no indication of widespread severe flooding, but monitoring continues.

Important reminders for residents

  • Do not remove sandbags or other protective measures currently in place.
  • Sandbags and sand remain available at the Municipal Garage located at 450 Chemin du Rang 5, L’Isle-aux-Allumettes for those who may need them.
