Water Level Management Update

Is your dam wide open?
You may notice that not all dams you see are wide open, but Parks Canada is moving as much water downstream as possible. The dams on the system are not of uniform capacity and there are many factors to consider, such as hydro generating stations that also pass water, and natural bottlenecks (such as the community of Minden on the Gull River). In addition, it takes multiple days for water to move through the system, and upstream dam operations need to be coordinated with those downstream.

For information regarding flood planning or protecting your home or property, please contact your local municipality.

Information on flood status in your area

What’s Parks Canada doing right now?
Parks Canada's water management team continues to actively monitor water levels and weather forecasts on a daily basis across the watersheds to inform our dam operations. The strategy for dam operations to manage levels is adjusted on a daily basis as the spring melt runs its course, and we communicate those actions to our partners responsible for flood forecasting and emergency preparedness.

Haliburton Reservoir System
Water levels on the Gull River and reservoir lakes continue to rise and more rain is expected over the weekend. However, the vast majority of the snow pack in the Haliburton watershed has melted.

The water flow on the Burnt River watershed has began to decline and the lakes on the Burnt river system are beginning to stabilize and fill to the their summer levels.

Parks Canada continues to conduct dam operations as appropriate, including flowing as much water as possible through the dams below Minden since April 10th.

Talbot River, Lake Simcoe and Severn River
The Talbot River system has stabilized and Parks Canada is now focussed on maintaining flows to maintain habitat for spawning fish at the Talbot fish sanctuary.

Levels on the Severn River and Black River remain high and well above flows that would be safe for navigation. Following peak water levels on the Black River, Parks Canada has increased flows for Lake Simcoe in an effort to return to an appropriate level range. Lake Simcoe is currently remains high.

Kawartha Lakes and Otonabee River
The recent rainfall elevated water levels slightly over the past few days however, water levels and flows have now resumed their gradual decline. Water levels on the Kawartha Lakes and the Otonabee River remain below the peak elevations observed last week.

Rice Lake and Trent River
Rice Lake was declining gradually however its decline was halted by recent rainfall and it now remains stable. Water levels on Rice Lake and the Trent River remain below the peak elevations observed last week.
