Spring Flood Outlook: Current Conditions Favourable for Slow Snow Melt Across the Watershed
(WCS – R03/2022)March 8, 2022 – The winter of 2021/22 is quickly coming to an end, and RVCA’s Flood Forecasting team is working closely with its municipal and agency partners to prepare for potential spring flooding.

Rain and Mild Temperatures Expected to Increase Water Levels Throughout Rideau Watershed
(WCS - RO6/2021)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…
