The Ministry of Natural Resources– Pembroke District is advising area residents that a Flood Warning is in effect for areas along the Ottawa River most noticeably from Pembroke to Arnprior until Friday, April 17, 2026 (if not updated/replaced).
Recent rainfall combined with warm temperatures has resulted in the melting of the snowpack and lake ice. This combined with forecasted precipitation and continued warm temperatures, will result in high water conditions as the freshet runoff moves through the system. This combined effect is causing the water levels and flows of the Ottawa River to rise significantly and may exceed flood levels in flood prone locations later this week. Water levels and flows upstream of Pembroke are expected to rise but remain below flood threshold levels at this time.
Residents that have been affected by high water and flow conditions in the past, should take necessary action to protect/secure any vulnerable property in proximity to rivers and lakes and closely monitor developing conditions and regularly check for updated messages.
The ministry is closely monitoring the weather and developing watershed conditions, further updates will be issued as appropriate.
