RVCA - Watershed Conditions Statement - April 18, 2023

Flood Warning – Update #3

Water Levels Continue to Decline Across the Rideau Valley Except in Upper Watershed Lakes

April 18, 2023

The previous Flood Warning and Flood Watch messages issued on April 6th, 8th and 11th 2023 are being updated to reflect current conditions. Unlike the Ottawa River Watershed which is currently experiencing high water conditions, the water levels and flows in the Rideau Valley Watershed are declining and approaching seasonal levels in all waterways except for Bobs Lake and Christie Lake. These lakes are near capacity and although the water level increases are now almost stabilized, the water levels may still increase with any significant rain.

The current forecast indicates between 25 mm and 35 mm of rain could fall next Sunday. As such, the water levels in Bobs Lake and Christie Lake will likely increase due to the forecasted rain. Parks Canada staff are closely monitoring the water levels in these lakes, and operations at the Bolingbroke Dam will take place as required, to balance the levels in Bobs Lake and Christie Lake. 
 
At this time, a FLOOD WARNING is being maintained for properties around Bobs Lake and Christie Lake.
 
The FLOOD WATCH issued on April 6th, 2023 for the properties around Big Rideau Lake is now over.

Residents in flood-prone or low-lying areas 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
   

This watershed conditions statement is in effect until Friday, April 28, 2023 and may be updated at that time unless the forecast or conditions change.
