Flood warnings remain in place for several communities along the Grand River as high water levels persist and more rainfall is forecast early next week.

The Grand River Conservation Authority (GRCA) says flood warning messages are being maintained for Brant County, Brantford, Six Nations of the Grand River and Haldimand County. A flood watch has also been issued for the remainder of the Grand River watershed.

The conservation authority says warm temperatures and rainfall beginning March 7 led to rapid snowmelt across the watershed, resulting in ice jams and flooding in some communities. While the risk of ice jams has now passed and river flows have begun to recede, water levels remain very high.

Officials say temperatures briefly dropped on March 13, bringing an additional five to 10 millimetres of mixed precipitation.

Temperatures are expected to rise again beginning Sunday, with another 10 to 15 millimetres of rainfall forecast for Monday. The GRCA says the additional precipitation could lead to further increases in river levels.

The conservation authority says the risk of flooding remains and officials will continue monitoring river conditions across the watershed.
