MEDIA RELEASE GRAND RIVER CONSERVATION AUTHORITY
The Grand River Conservation Authority (GRCA) is terminating the Flood Watch message previously in effect and is issuing a Watershed Conditions Statement – Water Safety message for the entire Grand River Watershed.
Weather forecast
Daytime high temperatures are expected to range from 7 to 12 degrees Celsius on Monday and 4 to 12 degrees Celsius on Tuesday, with warmer temperatures in the south and cooler temperatures in the north of the watershed. Above freezing temperatures are expected to continue through this week.
The snowpack across the watershed has been melting from recent rain and warm temperatures, which has led to increased water levels. With the forecasted above-freezing temperatures expected this week, the remaining snowpack will continue to melt and release water producing additional runoff resulting in further increases to water levels and flows.
No significant flooding is expected with this event; however, higher flows in local waterways will increase the risk in low-lying areas typically prone to flooding.
GRCA Reservoirs
GRCA reservoirs are within their normal operating range for this time of year and have flood storage capacity available. The reservoirs will be used to reduce downstream flooding.
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 all local waterways. As many students head into the March break this week, parents are reminded to keep their children and pets away from all watercourses.
Winter activities, including ice fishing, are now closed at all Grand River Conservation Areas. River ice cover is unstable due to thawing conditions and fluctuating water levels. The public is reminded to stay off of all ice-covered waterbodies, due to unsafe conditions.
River conditions and forecasts are being monitored closely, and any flood messages will be issued as needed.
This message will remain in effect until 12 p.m. on Friday, March 14, 2025.
