The Lower Thames Valley Conservation Authority (LTVCA) believes there's a chance of flooding in the region, according to a watershed condition statement released on Monday afternoon.
Environment Canada put a rainfall warning in place for much of southwestern Ontario, calling for 25 - 45 mm of rain by Tuesday afternoon. With recent snowmelt and rainfall already leaving the ground saturated and water levels elevated, the conservation authority is warning residents that local watercourses may spill over over.
"The amount of rainfall in the forecast is significant for this time of the year. The heavy rains could lead to ponding and localized flooding in low lying areas," LTVCA wrote in their flood outlook statement.
Water levels are expected to peak near Thamesville overnight, and in Chatham late Tuesday morning.
In downtown Chatham, LTVCA believes the river may rise enough to flood areas along the river, such as the dock and promenade. They say the McGregor Creek Diversion Channel may be needed for this rainfall event.
"People should take caution and avoid the river, ditches, and streams. The combination of slippery banks and fast-moving cold water can be dangerous," the conservation authority warned. "Standing water can also present its own unseen hazards. Children, pets and livestock should be kept away from the water."
