The St. Clair Region Conservation Authority issued a flood watch for the region on Monday morning, April 29.

SCRCA officials say upwards of 55 mm of rain have been received since Thursday and there is a possibility of 50 mm of rain forecast in the coming days.

“Heavy precipitation ranging from 20 to 55 mm in the lower reaches of the Sydenham River late last week resulted in rising water levels and flooding across the region,” SCRCA officials stated.

“Water levels remain elevated, however are falling as of this bulletin.”

The following roads are still impacted by high water levels:

– Waterworks Road between Courtright Line and Moore Line

– Stanley Line east of Kimball Road

“A low pressure system is expected to bring rain into southern Ontario starting this morning and into the coming days, with the potential of upwards of 50 mm of rain through to Wednesday evening,” SCRCA officials say.

“This precipitation has the potential to elevate water levels into natural floodplain areas, agricultural fields and parks. Soils already saturated from the rain this past week could contribute to ponding and increased runoff into watercourses.”

SCRCA officials say river banks are expected to be slippery, with possible minor erosion.

“Residents are reminded to avoid watercourses and flooded areas due to slippery banks and cold, swift moving water. Children and pets should be kept away from the water.”

The Conservation Authority continues to monitor watershed conditions and will issue advisories to municipalities and media should flood issues arise.

Municipal emergency response staff and road superintendents should monitor local conditions closely.

This message will remain in effect until Wednesday, May 1, 2019 unless otherwise updated.
