Parks Canada Water Management Update from the Rideau Canal

Please see below for the water management update from the Rideau Canal for May 4th, 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 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 weather forecast is predicting  a relatively dry period with less than 5 mm of rain.  


In the short term, water levels and flows are now receding. The Rideau Canal Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority.

Lake levels have stabilized and are near the average for this time of the year. Water levels in Colonel By Lake remain high but are receding.
