Rideau Valley Conservation Authority Watershed Conditions Statement – Water Safety
Heavy Rains will lead to Unsafe Conditionson Rivers and Lakes Throughout Rideau Watershed
December 20, 2018 — A significant weather system is expected to cross through our area over the next two days. Environment and Climate Change Canada is forecasting up to 40 mm of rain starting tonight, Thursday, December 20 through Friday, December 21. The forecast calls for above freezing temperatures during the day on Friday.
Water levels across the Rideau Valley watershed are generally normal to slightly below normal and the amount of snow cover is slightly below normal for this time of year. The forecasted heavy rain and warm air temperatures are expected to melt most of the snow on the ground. The combination of rain and snowmelt is expected to cause water levels and flows to increase rapidly and may result in flooding in area streams and low-lying areas.
Residents are advised to stay away from all rivers and watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain these dangers to their children.
Conservation Authority staff will continue to monitor conditions and issue further statements as conditions warrant.
