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 Otonabee River and Trent River above and below a much larger Rice Lake). 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.
What’s Parks Canada doing right now?
Information on flood status in your area
Parks Canada's water management team continues to actively monitor water levels, snow conditions 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, Minden and Northern Areas
Snow continues to melt in areas north of Minden and most of the Haliburton region experienced rainfall in the last two days, causing lake levels to rise. Parks Canada created room in the Haliburton lakes in the fall and winter months to accommodate the spring melt and average rainfall. Today, some controlled water releases were conducted through Twelve Mile and Horseshoe Lakes in response to Wednesday’s rainfall.
Water levels on Gull and Moore Lakes south of Minden remain high and Parks Canada has been flowing as much water as possible through the dams below Minden since April 10th. Talbot, Lake Simcoe and Severn River
Lake Simcoe has continued to rise over the past week. Reduced water flows on the Black River have allowed the flows to increase out of Lake Simcoe to the Severn River and into Georgian Bay. Thus, flows on the Severn River will increase. Kawartha Lakes, Peterborough and Otonabee
The dam at Lindsay remains open to reduce water levels on Lake Scugog.
Inflows caused by snow melt and rain continues to impact the upper Kawartha Lakes.
High water flows continue out of the Mississauga River into Lower Buckhorn Lake and water levels in the Kawartha Lakes above Peterborough remain high. Rice Lake and Lower Trent
Water levels in the lower Otonabee River, Rice Lake and the Trent River remain high. Water flows on the Trent River will remain consistent because, as inflows from the Crowe River decrease, flows out of Rice Lake will be increased, resulting in little change to the water flows on the Trent River.
