Rideau Canal National Historic Site

Some Parks Canada places have begun a safe, gradual reopening of some outdoor areas and services, including camping. Visitors are encouraged to plan ahead and be well-prepared for their visit. Details here.

Parks Canada's water management team continues to actively monitor water levels and flows, and weather forecasts across the Rideau Canal. These factors are used to determine dam operations on a daily basis for the Rideau Canal.

For up-to-date warnings and watches with regards to water levels in your region please follow your local conservation authority.

The Rideau Canal is an interconnected series of lakes, rivers, and artificial canal cuts stretching for 202 km from Ottawa south to Kingston, Ontario. The water in the system comes from two major watersheds: The Cataraqui and Rideau Rivers.

The canal, including its tributary lakes and rivers, is an important economic, environmental and recreational resource used by boaters, shoreline residents, businesses and vacationers every year. It also provides water for power generation, municipal water supplies, and agriculture and supports a tremendous variety of fish and wildlife.


Residents with questions or concerns pertaining to water levels and flows on the Rideau Canal should first refer to their respective Municipality, Conservation Authority or the Ontario Ministry of Natural Resources and Forestry. They are the primary source for relevant flood or drought forecasting information.

Further questions or concerns pertaining to water management on the Rideau Canal can be sent in writing by sending an email to rideau@pc.gc.ca. Please include specific details of the area in question and your contact information.

Please note the Parks Canada telephone line dedicated to water management is active and monitored only during the spring freshet (thaw) and in times of flooding.

Parks Canada maintains the Ontario Waterways Water Management InfoNet on the Rideau Canal website.

The InfoNet contains background information on water management practices, water management updates, frequently asked questions about water management, various reports on water management, and the most recent water level of lakes along both the Rideau Canal.
