Current:
Over the last 36 hours 30 to 50 mm of rain across the region has caused water levels to rise. Water levels are expected to continue to rise on the tributaries of the north branch of the Sydenham River, specifically in the Petrolia and Brigden areas and on Black Creek near Bradshaw. Water levels on the east branch are also increasing steadily at Alvinston and at Florence. Localized flooding is occurring at low lying areas, mostly in floodplain, agricultural and parkland areas. All watercourses are expected to be near or over top of bank conditions for the next few days.
Several roads will be closed this week. These roads include:
Pretty Road between Stanley Line and McCallum Line
Waubuno Road north of Bickford Line
Black Ash road South of Petrolia Line
Plowing Match Road between Rokeby Line and Petrolia Line
Fairweather Road between Rokeby Line and Shiloh Line
Fairweather Road between Aberfeldy Line and Oil Springs Line
Short Term:
Precipitation forecast for today calls for accumulations of near 10 mm across most parts of the watershed. Water levels will continue to rise with the additional precipitation resulting in high and near top of the bank conditions in most areas of Sydenham River for the next few days. Drains and smaller watercourses in upstream areas will experience localized flooding in some areas.
Municipal emergency response staff and road superintendents should monitor local conditions closely.
Residents are reminded to avoid watercourses and flooded areas due to saturated and slippery banks as well as the danger of swift moving water.
The St. Clair Region Conservation Authority will monitor the flood condition of the watersheds in the region and will provide warnings to municipal officials and media in the event conditions develop which could result in the potential of more severe flooding.
