(WCS – R05/2021)
September 22, 2021 – Environment Canada is forecasting rainfall amounts of 60 to 90 mm starting today through early Friday morning, with a few localities possibly exceeding 100 mm. The higher amounts are forecasted for the upper part of the Rideau Valley Watershed. This widespread rainfall event is due to a cold front and a moisture-laden low pressure system that will arrive from the American Midwest.

Because the Rideau Valley Watershed is currently in a ‘minor low water condition,’ all water levels and flows are currently below normal, so significant flooding is not expected. However, this large rain event will cause all water levels and flows to increase rapidly and 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 Tuesday, September 28, 2021 at 5 PM or until an update has been issued.
