Wet Weather in Most of the Rideau Watershed but Record Rain and Flooding in North Gower
Floodwaters Receding Slowly
The Rideau Valley Conservation Authority (RVCA) is conducting several hazard mapping studies on watercourses within the City of Ottawa and the RVCA area of jurisdiction. For some watercourses, old mapping will be updated; and for others, hazards maps will be created for the first time.
Project Status: Complete
Hogs Back to Kars & Kars to Burritts Rapids
The Rideau Valley Conservation Authority (RVCA) has completed two hazard mapping studies for the Rideau River: Hogs Back to Kars and Kars to Burritts Rapids. These studies update existing mapping in some areas and new mapping in others.
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. Both Rideau River studies look at identifying two main types of hazards along these stretches of the watercourse: flooding and slope stability.
When completed, the mapping will be used by the City of Ottawa and the Municipality of North Grenville 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 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.

Kindergarten Nature Program
Your Kindergarten class will be led through a series of age-appropriate, interactive activities suited to the season. Investigate what animals need to survive in different habitats through an outdoor scavenger hunt, get hands-on with animal pelts and skulls, and explore nature through fun play-based activities. Can be offered as a half-day or full-day program.
