Updated Flood Outlook & Flood Watch: Rain in Forecast Will Cause Water Levels to Increase Again Across the Rideau Valley Watershed

(WCS – R05/2020) March 27, 2020 –The short-term forecast is calling for rainfall amounts of 35 millimetres or more on Sunday and into Monday with above zero temperatures. As such, water levels and flows across the Rideau Valley Watershed are expected to increase again.

A FLOOD WATCH is being issued for properties around Christie Lake and Wolfe Lake. In these areas, residents should expect freshet like water levels and flows. Parks Canada staff are closely monitoring the water levels in Bobs Lake and Christie Lake, and operations at the Bolingbroke Dam.

A FLOOD WATCH continues for the low-lying areas along Stevens Creek and Taylor Drain in the Village of North Gower; however, water levels are expected to be less than those that have already been seen this spring.

A FLOOD OUTLOOK is being maintained/issued for the following areas:

  • Properties around Bob’s Lake and Tay River in the upper Rideau Valley Watershed. In these areas, residents should expect spring like water levels and flows. Parks Canada staff are closely monitoring the water levels in Bobs Lake and Christie Lake, and operations at the Bolingbroke Dam will take place as required, to balance the levels in Bobs Lake and Christie Lake.
  • Properties around the Long Reach (Burritts Rapids to Kars) of the Rideau River.
  • Properties around the smaller creeks and streams in the lower Rideau Valley Watershed, including the low-lying roads and waterfront properties adjacent to the Jock River (near Richmond).
  • Any connected creeks or ditches.

Extreme caution should be exercised by everyone when near local waterbodies. Please note that riverbanks are very slippery at this time of year and it’s quite easy for a child or adult to inadvertently fall into the water. Parents should inform their children of the risks and provide appropriate supervision.

Residents in flood prone or low-lying areas, historically susceptible to flooding, should continue to 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 April 9, 2020, at 5 p.m. and will be updated at that time unless the forecast or conditions change.
