MNRF Pembroke District Flood Warning Issued on May 11, 2018


MNRF Flood Warning  -  Pembroke District

Issued on May 11, 2018


The Ministry of Natural Resources and Forestry (MNRF) - Pembroke District is advising area residents that a Flood Warning remains in effect for the Madawaska River and the Ottawa River in Renfrew County.

Residents of Renfrew County should be advised that water levels and flows on the Madawaska River from Kamaniskeg Lake to Griffith and the Ottawa River from Westmeath to Arnprior remain high and are still above minor flooding thresholds.

For safety, all residents should keep a close watch on conditions, regularly check for updated messages and exercise caution near fast-moving rivers and streams. Any residents in areas prone to flooding should take appropriate action to protect their property, such as ensuring sump pumps are functioning and securing items that may float away as water levels rise. Anyone requiring sandbags or assistance should contact their local municipality.

The Ministry also advises extreme caution when using forest access roads for outdoor activities as many are seasonally inundated with water, prone to washouts and may be impassible due to current water levels.

MNRF is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate.
