Critical situation in Mansfield-et-Pontefract due to flooding
Critical situation in Mansfield-et-Pontefract due to flooding
The Municipality of Mansfield-et-Pontefract is informing residents about rising water levels in the Ottawa River and the Coulonge River, based on data published this morning by the Ottawa River Regulator and field observations. The situation remains critical as water levels continue to increase in several areas.
Coulonge Lake level
The current level of Coulonge Lake stands at 108.60 m, already exceeding the major flood threshold of 108.50 m. Forecasts suggest fluctuations between 108.55 m and 108.60 m in the coming days, though these figures may change depending on how the situation evolves. For reference, the moderate flood threshold is set at 108.00 m, while major flooding begins at 108.50 m—a level that has already been reached.
Coulonge River
The Coulonge River is also experiencing high levels, with a flow rate measured at 736 m³/s this morning at 8:00 a.m., slightly higher than last night (735 m³/s at 9:40 p.m.). Earlier forecasts had predicted around 650 m³/s today and 670 m³/s Monday, followed by a gradual decrease, but these projections will need to be reassessed.
Affected areas and on-the-ground issues
Several roads are currently flooded, significantly impacting residents and cottages in the area. The presence of onlookers in high-risk zones remains a concern. The Sûreté du Québec is on site to restrict access to dangerous areas.
An issue has also been reported at the culvert on Lac de la Truite Road, where water levels are extremely high and require constant monitoring.
Relocation and safety
Emergency services continue to respond in affected areas. Firefighters are recommending that impacted residents relocate as a precaution. Those without relocation options are encouraged to contact municipal authorities for assistance; so far, no such requests have been reported.
Residents needing help leaving an isolated, flooded, or water-surrounded property are asked to contact the fire chief at 613-401-7925. Emergency services will assess each situation and intervene safely if necessary.
In case of immediate danger, it is essential to call 911 without delay. Authorities stress never to attempt crossing a flooded road or leaving a high-risk area alone.
Residents can monitor water levels in real time through official platforms, including the Ottawa River (rivieredesoutaouais.ca) and the public safety monitoring system of the Ministère de la Sécurité publique du Québec.
Sand and bags are also available at 32 Lac de la Truite Road, and residents can call 613-401-7925 for more information.
The municipality thanks residents for their cooperation and vigilance as crews remain mobilized to ensure public safety.
