More Rain Forecast for Sunday
More Rain Forecast for Sunday
Water levels that were already high from rain on Sunday and Monday are expected to increase again if rain forecast for Thursday and Friday falls on the Rideau River watershed.
About 12 millimetres (mm) of rain fell overnight and as much as 40 mm more is expected. This could cause flows in the Rideau below Mooneys Bay to increase to about 320 cubic metres per second. While not an issue in the lower sections of the system, such flows typically mean flooding of low-lying areas on the Long Reach, the section of the river between Manotick and Burritts Rapids, with the access roads to the river side communities at risk.
High flows on the Tay River in Perth continue with most of the flow directed through the Little Tay which has caused flooding in Stewart Park. The construction site at Haggart Island Dam is being monitored closely.
The forecast rain can be expected to cause increased flows in the smaller streams such as Steven Creek. Residents in North Gower can once again expect to see the banks close to full through to next week.
Residents are advised to stay away from rivers as the forecasted weather may rapidly increase river flows, and cause slippery river banks. Parents are encouraged to explain these dangers to their children.

Project Status: Complete
The Rideau Valley Conservation Authority (RVCA) has completed a hazard mapping study for Kings Creek — a tributary of the Jock River — from the Brunton Side Road to the Jock River.
These maps are typically known as “floodplain mapping” and they show areas that are prone to natural hazards such as flooding, erosion and natural environment features such as wetlands.
When completed, the mapping will be used by the City of Ottawa and the Townships of Beckwith and Montague when updating their Official Plan and Zoning Schedules and in the review of development applications under the Planning Act. RVCA will also use the mapping to guide the review of development applications submitted under the Province’s Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation.
Members of the public are encouraged to attend our open house (date to be announced) and/or provide comments on the mapping below. Conservation Authority staff welcome historical records of past flood events, news clippings, photographs and even anecdotal stories to help confirm the reasonableness of calculations and resulting hazard mapping. For those unable to attend the open house, comments can be sent to Ferdous Ahmed, RVCA Senior Water Resources Engineer at .
These mapping studies are being completed as part of the City of Ottawa Hazard Mapping Project.
These studies are being done through a collaboration — known as the City of Ottawa Hazard Mapping Project — involving the City of Ottawa and the Mississippi Valley, Rideau Valley and South Nation Conservation Authorities. The City recognized a need to update its zoning schedules based on up-to-date flood risk mapping and has provided contributions enabling the Conservation Authorities to move ahead with these studies sooner than would otherwise be possible. The RVCA is currently working on several studies in the Ottawa area.
