Parks Canada Water Management Update from the Rideau Canal

Please see below for the Water Management Update for April 17, 2019.

“Parks Canada's water management team continues to actively monitor water levels and flows, and weather forecasts across the Rideau Canal.

Recently, Parks Canada launched the Ontario Waterways Water Management InfoNet on the Rideau Canal website at https://www.pc.gc.ca/en/lhn-nhs/on/Rideau/info/infonet 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 levels of lakes along both the Rideau Canal and the Trent-Severn Waterway.

Of specific note is the water levels tool within the InfoNet which provides lake levels data from the last 30 days and graphic representation of levels for the current year. The information comes from hydrometric gauges located at key points along both waterways and is vetted by trained and experienced Parks Canada water management staff.

This information is intended as supplemental information only. Stakeholders should continue to refer to their respective Conservation Authority or the Ontario Ministry of Natural Resources and Forestry as the primary source for relevant flood forecasting information specific to their area.


The five day forecast is calling for 50 mm of precipitation.


In the short term, water levels and flows will increase as a result of the forecasted amounts of rain. Saturated watersheds in the Upper Tay Watershed and northern part of Rideau River will contribute to the increased runoff amounts. The Rideau Canal Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority. 

Cataraqui River

Lake levels are declining but are expected to increase with the forecasted amount of rain.

Tay River

Bobs Lake and Christie Lake levels are above average, above full, are increasing and will continue to do so due to the recent significant rainfall and the forecasted rain. The levels on both lakes will continue to be monitored and the balancing of the high water will continue. Operations are conducted to increase outflows from Bobs Lake due to the high inflows from the recent rain event.  Flows on the lower Tay River will increase.

Rideau River

Wolfe Lake , Upper Rideau Lake and Big Rideau Lake levels are expected to increase. All the river reaches from Smith Falls to Burritts Rapids are above seasonal levels due to the recent rain event and are expected to increase with the forecasted precipitation.  Levels on the Long Reach remain above full and are expected to increase. The flows in the Rideau River are expected to increase.”

RVCA Releases its Annual Report

Media Release: “The Rideau Valley Conservation Authority (RVCA) has released its 2018 annual report, and among our many accomplishments from the past year, the planting of our six millionth tree stands tall.

“Every year we partner with landowners to reforest abandoned farm fields and other unused land,” said Scott Danford, manager of the reforestation program at RVCA. “Putting this land to work promotes wildlife and biodiversity, protects soil from erosion and improves water quality, while improving the look and value of these private properties.”

And that’s just one program of many at the Rideau Valley Conservation Authority, which monitors watershed health across a vast swath of land from Central Frontenac to Merrickville-Wolford and all the way to downtown Ottawa.”
