Water Level Management Update – April 11, 2017

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

For more information regarding watershed status, please visit the website of your local conservation authority. These are Kawartha Conservation, Otonabee Region Conservation Authority, Ganaraska Conservation Authority, Lower Trent Conservation Authority, Lake Simcoe Region Conservation Authority or, in all other areas of the Trent and Severn Watersheds, the Ontario Ministry of Natural Resources and Forestry.


Intermittent rainfall is forecast across the Trent-Severn Waterway region this week.  Otonabee Region Conservation Authority has issued a flood warning. Lower Trent Conservation Authority and Ontario Ministry of Natural Resources and Forestry Bancroft District have issued  flood watches.  A water safety statement has been released by the Kawartha Conservation and Lake Simcoe Region Conservation Authority.

Haliburton and Northern Areas

The Gull River and Burnt River have peaked or are close to peaking but may rise again depending on rainfall. The Central and Burnt Lake reservoirs are near capacity. Gull River reservoir lakes are at 77 per cent capacity. Little snow remains in the area.

Kawartha Lakes and the Otonabee River

The Kawartha Lakes levels are all near full. The Otonabee River flows are reaching average annual maximums.  

Rice Lake and the Lower Trent

The Rice Lake level is above average and will continue to increase.

Severn River

The Black River has peaked but may rise again depending on rainfall. Flows and water levels on the Severn River are expect to remain about the same as decreases in the Black River are offset by the release of water from Lake Simcoe.  Currently flows from Lake Simcoe to the Severn River is leakage only and discharges from Lock 42 have ceased.  The water levels on Lake Simcoe are above long-term average and are expected to increase.  Lake St. John dam is closed off to prevent back flow from the Black River.
