The Grand River Conservation Authority has a flood warning in place for the Nith River through Ayr.
The authority says the rain earlier this week has resulted in snowmelt and increased runoff into two local waterways.
Water flow through New Hamburg peaked slightly higher than expected early this morning and has now returned to below warning levels. F
lows through Ayr are expected to peak Wednesday afternoon and may reach Flood Warning Zone 2. Affected residents are being warned by municipal staff.
A flood watch remains in effect through the rest of the watershed with reservoirs in Belwood, Conestogo, Guelph, Luther, Woolwich, Laurel, and Shade’s Mills being used to store runoff in order to reduce flooding downstream.
