The high water levels on the Thames River should be expected into the middle of the week, according to a flood outlook from the Lower Thames Valley Conservation Authority.
Thunderstorms overnight Friday into early Saturday brought more rain than initially forecast with gauges around the watershed showing between 30 millimeters and 60 millimeters of rain by Saturday morning, said the LTVCA.
“Due to heavy rains, areas of ponding, standing water and localized flooding can be seen around the watershed,” the outlook stated.
Smaller watercourses have risen with some spilling over their banks and some other watercourses should still be expected to rise throughout the day Saturday, the LTVCA said.
“Since the Thames River was already higher than usual, watercourses tributary to the Thames River could have a difficult time draining the water away,” the outlook said. “Even higher than usual water levels should be expected in downstream areas near the river.”
The LTVCA said the Thames River in London has already risen higher than was seen earlier in March.
“As flows work their way downstream over the weekend and into early next week, it will flood the low-lying river flats adjacent to the river from Delaware down to Chatham,” the flood outlook said. “Flooding of the upper tablelands is not expected.”
The LTVCA advises people to take extra caution and avoid the river, ditches and streams since the combination of slippery banks and fast-moving water can be dangerous. Children, pets and livestock should be kept away from the water.
“As water levels rise, it is not safe to take shelter along riverbanks or in low-lying areas that are prone to flooding.”
The LTVCA will continue to monitor the situation and provide updates as necessary. The current advisory is in effect until Wednesday.
