The Grand River Conservation Authority has ended its flood watch for the Grand River watershed, signalling that conditions have returned to normal in Guelph and across the region as of April 9, 2026. With no active flood messages currently in place, residents can resume regular activities near local waterways without flood concerns.
The flood watch had been in effect since April 3, 2026, due to a combination of warm temperatures, rapid snowmelt, and approximately 70 mm of heavy rainfall that saturated the ground. The weather conditions led to elevated water levels in various areas, including the Speed River, which runs through Guelph.
To manage the high water levels and mitigate potential flooding downstream, the conservation authority utilized its network of seven major reservoirs, including the Guelph Reservoir located north of the city. These reservoirs, which also include Belwood, Conestogo, Luther, Woolwich, Laurel, and Shade’s Mills, were essential in controlling the flow of water throughout the watershed, which stretches from Dundalk in the north to Lake Erie in the south.
The Grand River Conservation Authority monitors conditions using a four-tier system. The termination of the recent flood watch means the region is no longer under any active alerts from the agency.
