Newsrooms please note:

A Watershed Conditions Statement is NOT a flood warning. Its purpose is to raise public awareness about a change or potential change in watershed conditions.

See below for watershed conditions terminology:

Watershed Conditions Statement: general notice of weather conditions that could pose a risk to personal safety or which have the potential to lead to flooding. There are two variations of these:

• Water Safety Statement: High flows, unsafe banks, melting ice or other factors could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
• Flood Outlook Statement: Early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion.

Flood Watch: Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.

Flood Warning: Flooding is imminent or already occurring in specific watercourses or municipalities. Municipalities and individuals should act to deal with flood conditions. This may include road closures and evacuations.

Water Conditions Statement Update #5:

FLOOD WARNING DOWNGRADE - Lower Ottawa River

May 18, 2023 – The Flood Warning for the Ottawa River issued on May 10, 2023 has been downgraded to a Water Safety Statement. 

Water levels along the Lower Ottawa River from Gatineau to the Grenville/Hawkesbury area are expected to continue decreasing over the coming days. 

Based on Ottawa River Regulating Committee forecasts, Ottawa River water levels are declining, and the rate of decline is slowing as they reach normal summer targets. There is no snow remaining in the watershed and reservoirs are now targeting summer levels. No significant rain is forecasted for the next couple of days.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain dangers to children. 

The Mississippi Valley, Rideau Valley, and South Nation Conservation Authorities monitor water levels and weather forecasts with the Ministry of Natural Resources and Forestry as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change. 

This Water Safety Statement will remain in effect until Thursday, June 1 at 5:00 p.m. No further updates will be issued unless forecasted levels or conditions change.

Communiqué sur les conditions de la rivière - mise à jour no 5 :

LEVÉE DE L’AVERTISSEMENT DE CRUE - Cours inférieur de la rivière des Outaouais

Le 18 mai 2023 - L'avertissement de crue pour la rivière des Outaouais émis le 10 mai 2023 a été rétrogradé à une déclaration de Sécurité aquatique.

On s'attend à ce que les niveaux d'eau le long du cours inférieur de la rivière des Outaouais, de Gatineau à la région de Grenville/Hawkesbury, continuent de diminuer au cours des prochains jours.

Selon les prévisions du Comité de régularisation de la rivière des Outaouais, les niveaux d'eau de la rivière des Outaouais diminuent, et le taux de baisse ralentit alors qu'ils atteignent les cibles estivales normales. Il ne reste plus de neige dans le bassin versant et les réservoirs approchent maintenant les niveaux d'été. Aucune pluie importante n'est prévue pour les deux prochains jours.

Il est conseillé aux habitants de ne pas s'approcher des cours d'eau dont le débit est élevé et dont les berges peuvent être instables. On demande aux parents d'expliquer ces risques à leurs enfants.

Les offices de protection de la nature de la vallée de la Mississippi, de la vallée de la Rideau et de la Nation Sud surveillent les niveaux d'eau et les prévisions météorologiques avec le ministère des Richesses naturelles et des Forêts dans le cadre du programme de prévision et d'alerte des crues. Des mises à jour sont transmises au fur et à mesure de l'évolution des conditions.

Cette Déclaration Sécurité Aquatique restera en vigueur jusqu'au jeudi 1er juin à 17 h. Aucune autre mise à jour ne sera émise à moins que les niveaux ou les conditions prévus ne changent.
