Flood warnings continue for the areas of Cambridge, Brantford and Haldimand county. But many areas in the northern portion of the Grand River watershed have been downgraded to a flood watch, according to an update release by the Grand River Conservation Authority (GRCA) Sunday morning.

It comes after 100 millimetres of rain fell in the Grand River watershed between 3 and 5 a.m. Friday, which caused flood warnings for many areas near the Grand River and Nith River.

"Flows remain significantly higher throughout Waterloo region, especially in the City of Cambridge," Cam Linwood, communications and development coordinator at GRCA, told CBC News Sunday.

Even though the northern portions of the Grand River watershed have been downgraded from a flood warning to a flood watch, river flows are still higher than what people would typically see this time of year, he said.

As a result, there is a significant amount of debris moving downstream. Municipalities should check bridges, dams and culverts for debris blockages.
