Following an unusually dry period, between 40 and 50 mm of rainfall has fallen across much of the upper and lower Grand River watershed in the last 24 hours leading to increases in flows within many rivers and streams. Environment Canada has issued warnings or special weather statements for much of the watershed that are advising of additional rain between 40 and 60 mm in localized areas for Saturday. The Grand River Conservation Authority’s (GRCA) major reservoirs have captured much of the runoff and will continue to do so, as the reservoirs are below their normal operating levels for this time of year due to the recent dry conditions.
While significant flooding is not expected as a result of this weather system, higher flows in rivers and streams will increase the risk of flooding in low-lying areas typically prone to spring flooding. River flows will remain higher than normal in the coming week, elevating the safety risk around waterways throughout the watershed. Tubing at Elora Gorge Conservation Area is currently open. However, note that tubing may close without notice at any time for many different reasons, including high river flows or thunderstorm activity. Should tubing close, those who have purchased tickets would be contacted directly via email.
The public is encouraged to exercise extreme caution around all local waterways. River levels can change very rapidly after periods of intense rain. Banks adjacent to rivers and creeks are very slippery and, when combined with fast-moving water, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses.
This message will remain in effect until Monday, June 28, 2021. Updated messages will be issued if necessary as conditions change.
