Flood Outlook & Updated Flood Watch - Warm Temperatures and Rain in Forecast Will Cause Water Levels to Increase Across the Rideau Valley Watershed

(WCS – R04/2020)

March 19 ,2020 – The short-term forecast is calling for rainfall amounts of 10 to 15 mm and high temperatures near 15 degrees Celsius on Friday, followed by below zero temperatures on Saturday, and then milder temperatures in the days following. No significant rain is in the short-term forecast after Friday.  With Friday’s rain and high temperatures, water levels and flows across the Rideau Valley Watershed are expected to increase everywhere and then decline again slowly with the cooler weather in the following days.

Some specific areas of concern are highlighted below:

A FLOOD OUTLOOK is being issued for the following areas:

  • Properties around Bob’s Lake, Christie Lake and Tay River in the upper Rideau Valley Watershed. In these areas, local 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 Wolfe Lake in the upper Rideau Valley Watershed.
  • 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)
  • and any connected creeks or ditches.

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 somewhat similar or possibly less than those that have already been seen this spring.

Extreme caution should be exercised by everyone when near local waterbodies. 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 2, 2020, at 5 p.m. and will be updated at that time unless the forecast or conditions change.
