'Highest January rainfall on record' causes flooding in Grand River watershed
Several roads and bridges across Waterloo region are closed due to flooding
A flood warning remains in effect for the entire Grand River watershed after a weather system brought up to 100 mm of rainfall to the area on Saturday, according to the Grand River Conservation Authority.
The storm resulted in substantial flooding for communities in the northern and central parts of the watershed, the GRCA said in a statement.
As of Sunday afternoon, the GRCA said river flows in these parts of the watershed had begun to recede but are expected to remain higher than normal for this time of year.
Meantime, flows in the southern Grand River watershed are expected to increase throughout the weekend and cause "significant" flooding in certain areas before receding this week.
Communities along the Grand River through the southern watershed such as Paris, Brantford, Caledonia, Cayuga, and Dunnville should prepare for flooding similar to June 2017, the GRCA said.
The weekend weather event produced the highest January rainfall on record for this part of the province, the GRCA said.

GRCA used its major reservoirs in Belwood, Conestogo, Guelph, Luther, Woolwich, Laurel, and Shade's Mills to manage runoff and reduce flooding downstream.
On Sunday afternoon, GRCA said it had started to release water from these reservoirs. River flows through the watershed are expected to remain high throughout the week as runoff from the storm moves through the system.
People are cautioned to stay away from all waterways due to extreme risk caused by slippery riverbanks and bad weather conditions.
"Parents are encouraged to keep their children and pets away from all watercourses," the GRCA said.
Cameron Linwood, communications co-ordinator for the GRCA, said the January flood follows a trend of greater climate variability the conservation authority has monitored in recent years.
"What we're seeing now is extreme events happening throughout the year," whether that's a January rain storm or a significant ice jam, he said.
"It used to be somewhat more predictable. Now we're seeing them happening all year round," Linwood said.
