Forecasted Precipitation May Increase Water Levels and Flows and Cause Unstable Ice Throughout Rideau Watershed
(WCS – R07/2020)
December 24, 2020 — Environment Canada is forecasting between 30 and 50 mm of rain starting today and continuing overnight throughout the Rideau Valley watershed.
Although no significant flooding is anticipated, water levels and flows are expected to increase in all waterways in the Rideau Valley Watershed. Depending on how much rain falls, residents who are adjacent to the smaller creeks and streams are advised to keep a close watch on water levels and flows and should take the necessary precautions to protect their property, such as:
- Ensuring sump pump is clear, in good working condition and has a backwater valve
- Ensuring easy access to a portable backup generator and pump
With the expected increase in water levels and flows in the coming days, ice cover on lakes, ditches, local streams and rivers will be unstable. Extreme caution should be exercised by everyone when near local waterbodies. Parents should inform their children of the risks and provide appropriate supervision.
This watershed conditions statement is in effect until Monday January 4, 2020 at 5 PM or until an update has been issued.
