Drivers in Wilmot Township may have to take a different route to get around due to flooding. Several roads were closed on Sunday as a safety precaution: On Saturday, the Grand River Conservation Authority issued a flood warning for New Hamburg, Ayr and West Montrose as watercourses swelled due to snowmelt and recent rainfall. “River flows are expected to reach Flood Warning Zone 1 in New Hamburg during the late evening of Saturday, March 7, and may extend to Flood Warning Zone 2 in the early morning of Sunday, March 8,” a notice from the conservation authority said. In West Montrose, flooding is possible in Flood Warning Zone 1 late Saturday evening. Meanwhile, flooding is possible in Flood Warning Zone 1 in Ayr on Sunday, with the potential to extend into Flood Warning Zone 2 later in the day.
