The CCGS Griffon will be breaking up ice jams near Port Maitland, ON and the mouth of the Grand River today, where is connects to Lake Erie. This is an effort to reduce flood risk due to ice restriction of water as it passes down stream today through Wednesday.
Communities along the Grand River and its tributaries should pay close attention to local statements and updated warnings from the Conservation Authority. A flood warning remains in effect for the entire watershed.
Ice jams remain in place on the Grand River in Cambridge (pictured), Brantford, and Cayuga.
Flooding as a result of these ice jams can occur quickly and without warning.

The flood concern is expected to peak Wednesday morning, before cooler temperatures and mixed precipitation arrives.
Total rainfall amounts of 40-60mm is expected. Locally higher amounts are expected east of Lake Huron.
