FOR IMMEDIATE RELEASE

Pretty River Dike Safety Review begins this June

UTOPIA, Ontario (May 26, 2026) – The Nottawasaga Valley Conservation Authority (NVCA) will be conducting a safety review of the Pretty River Dike to assess its structural stability.

The Pretty River Dike, constructed in the 1970s, plays a critical role in safeguarding the community by reducing the risk of flooding in downtown areas of Collingwood. When maintained properly, it provides essential protection for residents, homes, businesses, and key community assets – including the Collingwood Public Library, Collingwood Museum, Town Hall and Central Park.

The safety review will involve two weeks of borehole drilling to confirm the structural integrity of the dike. Equipment will also be installed to monitor internal pressure within the dike structure. A drill rig will be traversing River Trail and may impact residents’ access to limited portions of the trail.

“When using the trail system along the Pretty River Dike, residents are reminded to be vigilant around the drill rig, as it can pose a hazard to unauthorized individuals,” said Dalia Al-Ali, Manager of Engineering Services at NVCA. “The work will begin in mid-June and should present minimal disruption to trail users. Signage and safety measures will be in place to direct trail users to avoid the impacted area.”

The Pretty River Dike safety review will help NVCA identify required rehabilitation and maintenance needs which will then be addressed by NVCA in the coming years.
