Updated Flood Outlook & Flood Watch: 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.
"Rideau Valley Conservation Authority is a partnership of municipalities within the Rideau Valley watershed created under the Conservation Authorities Act to deliver a range of programs in watershed management and natural resource conservation."

WATER SAFETY STATEMENT — Lower Ottawa River / SÉCURITÉ AQUATIQUE — Cours inférieur de la rivière des Outaouais
March 30, 2020 — A Water Safety Statement is being issued for areas along the Lower Ottawa River. Based on current snow cover and weather forecast, it’s anticipated that levels and flows from Arnprior to Hawkesbury will remain within the normal range of fluctuations associated with the spring freshet period.
The Ottawa River Regulating Committee indicates that with warming temperatures and forecasted precipitation, increases in flows and levels are expected to continue and may cause minor flooding in low-lying areas over the coming weeks depending on the temperatures and precipitation received. Levels are currently expected to remain below flood thresholds.
Throughout the freshet period, the combination of heavy rainfall and snowmelt may result in rapid increases in water levels and flows on the main stem of the Ottawa River from Mattawa down to the Montreal Region.
Residents in flood-prone areas are encouraged to closely follow evolving conditions and to take necessary measures. Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain dangers to children.
The Mississippi Valley, Rideau Valley, and South Nation Conservation Authorities monitor water levels and weather forecasts with the Ministry of Natural Resources and Forestry as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.
The Ottawa River Regulating Committee will be reassessing forecast conditions and providing hydrological condition updates on its website daily at ottawariver.ca/forecasts/.

Le 30 mars 2020 — Une déclaration de sécurité aquatique est publiée pour les zones situées le long du cours inférieur de la rivière des Outaouais. Selon la couverture de neige actuelle et les prévisions météorologiques, on prévoit que les niveaux et les débits d'eau d'Arnprior à Hawkesbury resteront dans la fourchette normale des fluctuations associées à la période des crues printanières.
Le Comité de régularisation de la rivière des Outaouais indique qu'avec le réchauffement des températures et les précipitations prévues, l'augmentation des débits et des niveaux devrait se poursuivre et pourrait provoquer des inondations mineures dans les zones basses au cours des prochaines semaines, en fonction des températures et des précipitations reçues. Les niveaux devraient actuellement rester en dessous des seuils d'inondation.
Tout au long de la période de crue, la combinaison de fortes précipitations et de la fonte des neiges pourrait entraîner une augmentation rapide des niveaux et des débits sur le cours principal de la rivière des Outaouais, de Mattawa jusqu'à la région de Montréal.
On encourage les résidents des zones inondables à suivre de près l'évolution des conditions et à prendre les mesures nécessaires. Il est conseillé aux résidents de se tenir à l'écart des cours d'eau où les débits sont élevés et où les berges pourraient être instables. On recommande aux parents d'expliquer les dangers aux enfants.
Les offices de protection de la nature des rivières Mississippi, Rideau et Nation Sud surveillent les niveaux d'eau et les prévisions météorologiques avec le ministère des Richesses naturelles et des Forêts dans le cadre du Programme de prévision et d'alerte des crues.
Des mises à jour sont émises en fonction de l'évolution des conditions.
Le Comité de régularisation de la rivière des Outaouais réévaluera les prévisions et publiera quotidiennement des mises à jour des conditions hydrologiques sur son site Web à ottawariver.ca/forecasts/.
