March 29, 2019 – Since early March, we have experienced a very gradual snow melt with limited precipitation across much of the Rideau Valley Watershed.  In the lower Rideau Valley Watershed (North Grenville and Ottawa) and in the Tay Valley Watershed, there still remains above average snow pack which indicates a potential for above average flooding in low lying areas adjacent to any rivers, creeks or ditches.

The current weather forecast indicates that it will remain cool (near freezing) for Saturday and Sunday with a mix of rain, freezing rain, and snow on Saturday.  However, there is uncertainty about how much will fall as rain, freezing rain or snow.  The current weather forecast also indicates that it will start to warm up next Tuesday with above zero temperatures during the day and night. 

Based on the above forecast, water levels and flows are expected increase this weekend in all waterways in the Rideau Valley Watershed. The degree of increase will depend on what type of precipitation occurs.  If it’s mostly rain, then flooding could occur in the following areas:

• The smaller creeks and streams in the lower Rideau Valley Watershed. This would include the low-lying roads and waterfront properties adjacent to the Jock River (near Richmond) and Stevens Creek (near North Gower), and any connected creeks or ditches.
• The Long Reach (Burritts Rapids to Manotick) of the Rideau River. In particular, access to Hilly Lane, Cedar Beach, Rideau Glen and other neighourhoods on that reach of the river can be expected to be compromised.

City of Ottawa crews are continuing with their annual ice removal program on the Rideau River between Rideau Falls and Bronson Avenue. City crews are busy with ice breaking activities (for more information: City of Ottawa information at 311).

With the changing levels that can be expected over the coming days, ice cover on lakes, ditches, local streams and rivers will continue to 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.

As the temperatures continue to warm up, the potential for ice jams still remains high in some local streams and rivers, as flows could quickly increase before the ice can melt. Residents are advised to monitor the river closely as spring progresses for signs of ice jams. RVCA staff will be monitoring conditions but we always welcome any unique observations from watershed residents.

There is also a concern for flooding along roadways due to current snow/ice build up on roadside ditches.

Residents in flood prone or low-lying areas, 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

March 19, 2019 – Despite some gradual snow melting over the last two weeks, the snowpack throughout the Rideau Valley Watershed remains above average so there is still a potential for above average flooding this spring across the Rideau Valley Watershed, especially in low lying areas which have flooded in the past. However, the current weather forecast until end of March is indicating that daytime temperatures with single digit highs and below zero conditions at night with very little precipitation, so no significant flooding is anticipated in the next week or so.  This could change if the forecast changes (i.e., significant rainfall or higher temperatures).

Water levels on lakes and flows in the streams are presently about normal for this time of year. Parks Canada staff who manage the water levels for the Rideau Canal have indicated that the levels will be maintained in the coming weeks to allow for water storage in the upper watershed lakes as the snowpack continues to melt.

City of Ottawa crews are continuing with their annual ice removal program on the Rideau River between Rideau Falls and Bronson Avenue. Ice blasting is now complete and City crews are busy with ice breaking activities (for more information: City of Ottawa information at 311).

March 6, 2019 – The winter of 2018-19 has been an old-fashioned winter with lots of snow (over 250 cm to-date) and no significant thaw events. As such, the snowpack throughout the Rideau Valley Watershed is well above average. Current conditions at several RVCA snow course sites are indicating near record water content amounts in the snow for this time of year, generally not seen since the late 1970s. 

Based solely on the fact we have above average water content, there is a potential for above average flooding this spring across the Rideau Valley Watershed, especially in low lying areas which have flooded in the past. However, the two other key factors influencing actual flood conditions are precipitation and temperatures as we move through March and into April. The current short-term forecast does not indicate any significant precipitation or above-seasonal temperatures; however, we know the daily temperature will begin to increase as we move through March.

Water levels on lakes and flows in the streams are presently at or slightly below normal for this time of year. Parks Canada staff who manage the water levels for the Rideau Canal have indicated that the levels will be maintained or lowered in the coming weeks to allow for water storage in the upper watershed lakes once the snowpack starts to melt.

City of Ottawa crews have begun the annual ice removal program on the Rideau River between Rideau Falls and Bronson Avenue. Crews will work to keep the ice from reforming until the spring freshet occurs (for more information: City of Ottawa information at 311).

With the changing levels that can be expected over the coming weeks, ice cover on lakes, ditches, local streams and rivers will continue to 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.
