(WCS – R01/2024) - The Rideau Valley Conservation Authority is issuing a WATER SAFETY message for the entire Rideau Valley Watershed due to the potential for localized ice jams which could cause sudden water level increases and flooding.
Following a period of warmer than usual temperatures and then a significant snowstorm, Environment Canada is forecasting cold temperatures, as low as -20°C overnight, for the next week with little precipitation. The forecast also indicates sustained winds are expected, which will cause wind chill temperatures. Many waterways are not yet frozen and with the onset of colder weather, there is a potential in localized areas for ice to form quickly, especially on water structures such as bridge abutments, piers, riverbanks, and channels. This could obstruct the flow of water and cause local water levels to rise. Any sudden water level increases may cause localized flooding. Parks Canada, which manages water levels for the Rideau Canal waterway, is also undertaking necessary dam operations in some areas which may increase the potential for rapid ice formation during this cold spell.
Residents are advised to stay away from all rivers and watercourses in the vicinity of any ice jams and high water areas. Parents are encouraged to explain these dangers to their children.
This watershed conditions statement is in effect until Thursday, January 25, 2024 at 5 PM and may be updated at that time unless the forecast or conditions change.
