(WCS – R06/2024)
April 15, 2024 – A Flood Outlook Statement is being issued for the Upper Rideau Valley Watershed.

Since early April, two large weather systems have brought between 60 to 90 mm of precipitation across the Rideau Valley Watershed. The highest precipitation amounts (90 mm) fell across the Upper Rideau Valley Watershed near Bob’s and Christie Lakes and the Tay River. The weather forecast indicates another 10 to 15 mm of precipitation for the next week.

The significant precipitation received since early April has resulted in increased water levels and flows in all waterways in the Rideau Valley Watershed. 

Based on the above, a FLOOD OUTLOOK is being issued for the properties around Bobs and Christie Lakes in the Upper Rideau Valley Watershed. The water levels are expected to exceed full supply levels by this coming weekend and may result in flooding for low-lying areas. Parks Canada staff are closely monitoring the water levels in Bobs Lake and Christie Lake. Operations at the Bolingbroke Dam will take place as required to balance the levels in Bobs Lake and Christie Lake.  

Residents in low-lying areas near Bobs and Christie Lakes that are historically susceptible to flooding 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
  • Ensuring downspouts are clear and the outlet is at least 3 metres from the dwelling 
  • Securing items that might float away as flows increase 
  • Removing valuable items from basements or lower floors that could be subject to flooding
  • Keeping emergency phone numbers handy
  • Familiarizing yourself with your municipality’s Emergency Preparedness Plan

With the elevated conditions, potential exists for further impacts if significant additional rain were to occur before the water levels and flows begin to recede.

Extreme caution should be exercised by everyone when near local waterbodies. Parents should inform their children of the risks and provide appropriate supervision. Pets should be leashed near all bodies of water. 

This watershed conditions statement is in effect until Wednesday, April 24, 2024 at 5 PM unless the forecast or conditions change.
