The St. Clair Region Conservation Authority has ended a flood warning across the region, but a water safety bulletin has been issued.
SCRCA officials say the McKeough Dam gates are fully open and wind-driven minor flooding is expected.
“Flooding from last weekend’s rain event has receded and the McKeough Dam gates have been fully opened,” SCRCA officials stated.
“Water levels remain elevated in Wallaceburg at the outlet of the Sydenham River, owing to high water levels on the St. Clair River and Lake St. Clair slowing the movement of water out of the watershed.”
SCRCA officials added: “Winds are anticipated from a southerly direction in the afternoon, changing to southwesterly in the evening. Winds from these directions have the potential to cause a backwater effect in the Wallaceburg area, further slowing the movement of water out of the river and contributing to elevated water levels. Minor flooding over the top of the bank is possible in this area.”
Wind gusts are forecasted upwards of 70 km/h with sustained winds around 40 km/h, changing from a south/westerly direction to northerly by Sunday afternoon, SCRCA officials say.
“The winds over the course of the next 24-48 hours are expected to affect residents along the Lake St. Clair and Lake Huron shorelines and may cause increased wave action and possible erosion,” SCRCA officials stated.
“The forecast is calling for 15-20 cm of snow with an additional 5 mm of rain. 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 Monday, January 20, 2020 unless otherwise updated.
