The Long Point Region Conservation Authority (LPRCA) has issued a Watershed Conditions Statement – Flood Outlook for the entire watershed, including the Lake Erie shoreline within its jurisdiction, as a powerful weather system moves into southern Ontario.
A low-pressure system is expected to track through the region, bringing above-freezing temperatures and significant rainfall.
The region saw heavy rain yesterday (Sunday) with strong southwest winds in the forecast for today (Monday), creating conditions that could lead to elevated water levels, shoreline impacts, and localized flooding.
The rain, combined with existing snow and ice, is expected to increase runoff into creeks, rivers, and low-lying areas.
Behind the system, sustained southwest winds of 50 to 60 km/h, with gusts reaching 80 to 100 km/h, are expected to elevate water levels along Lake Erie, particularly in Haldimand County.
Residents living near shorelines and flood-prone areas are urged to use caution and avoid areas experiencing strong wave action or rising water levels.
At the same time, the Grand River Conservation Authority (GRCA) has issued a Flood Watch for the Nith River Subwatershed, while a Watershed Conditions – Water Safety message remains in effect for the rest of the Grand River watershed.
The GRCA says runoff from melting snow combined with rainfall could lead to higher water levels, particularly in low-lying and flood-prone areas.
Municipal flood coordinators in New Hamburg and Ayr are being advised to monitor conditions closely and prepare for potential flooding.
Major reservoirs including Belwood, Conestogo, Guelph, Luther, Woolwich, Laurel, and Shade’s Mills currently have capacity to help reduce downstream flooding.
Parents are also reminded to keep children and pets away from watercourses during this period.
