Parks Canada: Reduced Water Levels on the Rideau Canal

Ontario's Rideau Canal is currently experiencing reduced water levels in the Southern Sector of the system (from Narrows Lockstation to Lake Ontario) due to a lack of precipitation and evaporation caused by unseasonably high temperatures.

Navigation is currently not impacted and boat traffic can continue to move freely across the entire system.

Parks Canada's water management staff is working with its partners to manage water flows on a system-wide basis to ensure sufficient water levels to meet the broad range of needs including recreation, municipal water supply and fisheries management.

Over the past two months, eastern Ontario has experienced unusually low precipitation levels. According to The Weather Network, Ottawa (counting both snow and rainfall for the growing season so far) has received slightly more than half the normal amount of precipitation typically experienced there between April 1 and June 26.

The CBC reported this week that the Grand River Conservation Authority (GRCA) has recommended residents to reduce their water consumption by 10 percent because of dry conditions across the watershed. The GRCA manages water and other natural resources on behalf of 39 municipalities and close to one million residents of the Grand River watershed, which is the largest in southern Ontario. The Grand flows from Dufferin County in the north to Lake Erie in the south.

Parks Canada says developments regarding water levels will be communicated through the Rideau Canal website and social media, and if required, through a Canadian Coast Guard Notice to Shipping.
