The City of Brantford declared a State of Emergency. In Cambridge, ice and debris damaged city infrastructure, communications and a water main. Up to 2,200 homes and 4,900 residents were impacted by an evacuation order. The first warning was issued on February 16th but by February 18th a warning was issued for the entire watershed. The Grand River Conservation Authority issued flood warnings for several communities including Brantford, Cambridge, North Dumfries and Brant County. Ice jams tended to form in Cambridge, Brantford and Cayuga ? in Cambridge the ice jam measured 5 km upstream. The combination of frazil ice, ice jams, 40-60 mm of rain, and 50-70mm of melting snowpack caused the water levels of the Grand River to rise rapidly. In addition to this, temperature drops led to the formation of frazil ice ? heavy slush in rivers. The winter of 2018 was one of the coldest on record, which created a very strong icepack throughout the Grand River watershed in Ontario.
