Rain and Mild Temperatures Expected to Increase Water Levels Throughout Rideau Watershed

December 10, 2021

Environment Canada is forecasting rainfall amounts of 20 to 40 mm starting the evening of Friday, Dec. 10 and continuing through Saturday night. This forecasted rainfall together with mild temperatures will melt snow and create runoff, causing all water levels and flows to increase throughout the Rideau Valley Watershed.

Because of a wet fall season, most water levels and flows are currently above normal. Although this rain and snow-melt event will not cause significant flooding, it could cause localized flooding in small watercourses, urban areas and ditches. 

The RVCA reminds the public to exercise extreme caution around all waterbodies and remind children about the dangers of playing near open water. Residents are reminded to make sure their sump pumps are in good working condition and to help reduce ponding by keeping ditches, culverts, and storm drains clear of obstructions.

This watershed conditions statement is in effect until Friday, December 17, 2021 at 5 PM or until an update has been issued.
