(WCS - RO6/2021)
December 10, 2021 – Environment Canada is forecasting rainfall amounts of 20 to 40 mm starting the evening of Friday, Dec. 10 and continuing through Saturday night. This forecasted rainfall together with mild temperatures will melt snow and create runoff, causing all water levels and flows to increase throughout the Rideau Valley Watershed.

Because of a wet fall season, most water levels and flows are currently above normal. Although this rain and snow-melt event will not cause significant flooding, it could cause localized flooding in small watercourses, urban areas and ditches.  

The RVCA reminds the public to exercise extreme caution around all waterbodies and remind children about the dangers of playing near open water. Residents are reminded to make sure their sump pumps are in good working condition and to help reduce ponding by keeping ditches, culverts, and storm drains clear of obstructions. 

This watershed conditions statement is in effect until Friday, December 17, 2021 at 5 PM or until an update has been issued.

(WCS – R01/2022)
February 16, 2022 – Environment Canada is forecasting mild temperatures, with 15 to 25 mm of rain starting late today through Thursday afternoon followed by much cooler temperatures and possible snowfall accumulations of 10 to 20 cm of snow before mid-day on Friday. This weather event will likely result in elevated water runoff to all waterways because of snow melt and high rainfall amounts before freezing up again.

Although no significant flooding is anticipated, water levels and flows are expected to increase in all waterways in the Rideau Valley Watershed. Depending on how much snow melts and rain falls, residents who are adjacent to the smaller creeks and streams are advised to keep a close watch on water levels and flows and 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

With the expected temperature changes and increase in water levels and flows in the coming days, ice cover on lakes, ditches, local streams and rivers will 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.

This watershed conditions statement is in effect until Wednesday February 23, 2022 at 5 PM or until an update has been issued.

March 8, 2022 – The winter of 2021/22 is quickly coming to an end, and RVCA’s Flood Forecasting team is working closely with its municipal and agency partners to prepare for potential spring flooding. 

To date, the spring flood outlook remains positive. December was generally mild with below average precipitation, while temperatures in January were well below normal. Precipitation in January was also below normal but a large storm mid-January left almost 50 cm of snow on the ground. In February, both the temperature and precipitation amounts were very close to normal. Early March conditions at several RVCA and Parks Canada snow course sites indicated near normal amounts of snow for this time of year. However, some snow was lost due to mild temperatures on Sunday, March 6. Water levels and flows across the watershed are now near normal for early March.

The current short-term weather forecast indicates daytime high temperatures near zero and night-time low temperatures below zero for the next five days. The forecast also indicates some mixed precipitation during this same time-period. 

If the temperatures come as forecast over the next few days, limited snowmelt is expected across the Rideau Valley watershed and is unlikely to cause any significant flooding. Parks Canada staff who manage the water levels for the Rideau Canal have indicated that the levels in lakes are expected to rise in the upper watershed lakes as the snowpack begins to melt. 

Beyond the short-term forecast discussed above, it is difficult to predict what’s in store for flooding conditions in the Rideau Valley Watershed, since flood conditions are a result of natural processes that vary from year to year based on snowmelt, temperature increases and precipitation events. It is important to be prepared for possible flood conditions for the next few weeks as the winter comes to an end.

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 call City of Ottawa’s information line at 311).

With rising water levels expected over the coming weeks, ice cover on lakes, ditches, local streams, and rivers will 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. Keep pets leashed near waterbodies, as well.

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 March 15, 2022, at 5 p.m. and will be updated at that time unless the forecast or conditions change first.

March 15, 2022 – The current short-term weather forecast indicates warm daytime temperatures this week, with Thursday’s temperature above 10 degrees Celsius, and night-time low temperatures near zero. The short-term forecast also indicates that a substantial rain event could occur on Sat. March 19.

Current conditions at several RVCA and Park Canada snow course sites indicate near normal amounts of snow for this time of year.

If the temperatures come as forecast in the coming days, significant snowmelt is expected across the Rideau Valley watershed. This will increase water levels and cause some flooding in all low-lying areas, especially those identified below. Forecasted rain later in the week may further increase water levels throughout the watershed. Parks Canada staff who manage the water levels for the Rideau Canal have indicated that the levels in lakes are expected to rise in the upper watershed lakes as the snowpack melts.

Some specific areas of concern are highlighted below:

A FLOOD WATCH is being issued for all the low-lying areas along Stevens Creek and Taylor Drain in the Village of North Gower.

A FLOOD OUTLOOK is being issued for all the low-lying areas around the smaller creeks and streams in the Rideau Valley Watershed, including any connected creeks or ditches.

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. 

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.
