Grand River Conservation Authority (GRCA) issued a flood warning for areas in the County of Brant on Monday, March 9, 2026.
A Flood Watch remains in effect for the the rest of the Grand River watershed.
Weather forecast
Warm weather and rain over the past three days has melted the snowpack and has led to ice jams and flooding. The air temperature is expected to remain above zero today approaching 7 or 8 ºC in the northern part of the watershed and the mid-teens tomorrow and Tuesday, which will continue melting the remaining snowpack. River levels are elevated and additional runoff from snowmelt may cause river flows to increase.
Flood Warning the County of Brant
Residents are encouraged to refer to the Flooding section of the County of Brant website and view the online mapping tool, for information regarding flood warning zones.
River flows are expected to reach Flood Warning Zone 2 on the Grand River from Glen Morris to Paris (Penman’s Dam) the morning of Monday, March 9, and possibly into Tuesday, March 10.
River flows are expected to reach Flood Warning Zone 2 on the Grand River from Paris (Penman’s Dam) to Onondaga on the afternoon of Sunday, March 8, and may extend into Flood Warning Zone 3 on the afternoon of Monday, March 9.
River flows are expected to reach Flood Warning Zone 2 on the Nith River in Paris in the early morning of Monday, March 9.
Flood Watch Remains in effect for the remainder of the Grand River watershed
The snowpack across the watershed has been melting from recent warm temperatures, which has led to increased water levels. Additional melting of the snowpack is expected in the coming days. Higher flows in local waterways combined with runoff from this event is increasing the risk of flooding in low-lying areas typically prone to flooding. Some areas of the river system are still ice covered which poses a possible risk of flooding related to ice jams. Municipal flood coordinators should monitor areas where ice jams are known to occur.
Stay safe
High flows and unstable ice conditions will increase the safety risk around rivers and streams throughout the watershed. The public is encouraged to exercise extreme caution around local waterways. Parents are reminded to keep their children and pets away from watercourses. The public is reminded to stay off ice-covered waterbodies, due to unsafe conditions.
River conditions and forecasts are being monitored closely, and any additional flood messages will be issued as needed.
This message will remain in effect until 12 p.m. on Wednesday, March 11, 2026.
