Yesterday and overnight, the region received around 30 mm of rainfall. There is an additional 5
to 10 mm of rainfall expected for the rest of today. The ground was already saturated from
several smaller rainfall events received over the last few days. As a result, most of this rainfall
has run off directly into the region’s watercourses.
This rainfall has caused several local watercourses to reach bank full conditions. Some
watercourses, such as McGregor Creek upstream of Chatham, have spilled their banks and are
flooding the low lying adjacent areas. Water levels can be expected to continue to rise
throughout the day. The Conservation Authority is operating the McGregor Creek Diversion
Channel which was designed to reduce flood risk in south Chatham and the surrounding areas.
While this rainfall event is causing high water levels on the region’s smaller watercourses, we do
not expect to see flooding from the Thames River itself.
People should avoid ditches, streams, creeks and the river as a combination of slippery banks,
and fast flowing water is dangerous. People are encouraged to keep their children and animals
away from watercourses at this time.
The Lower Thames Valley Conservation Authority will continue to monitor the situation and
provide updates as required.
