Parks Canada – Water Level Management Update


Please see below for the water management update from the Rideau Canal for Friday, January 10th, 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 Weather Network is currently forecasting 50 to 75 mm of rainfall across the Cataraqui River and Rideau River Watersheds.  The bulk of this rainfall is anticipated to come Saturday. 


The snow on the ground is variable across the Rideau Canal.  In general, the amount of snow increases as you move North from Lake Ontario.  Snow amounts in the Cataraqui Watershed are low while snow amounts in the Rideau Watershed range from low to moderate.  The warmer weather in combination with the forecasted rainfall will likely remove all the snow.  Flows in the Rideau Canal are anticipated to rise significantly and water levels are expected to increase in all lakes and river reaches.

The Rideau Canal Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority
