Water Level Management Update – Tuesday, March 27, 2018
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.
The total amounts of precipitation in March have been less than normal resulting in lower than average snow pack for this time of the year. The 7 day forecast suggests various amounts of precipitation ranging from 14 to 23 mm of rain and temperatures below 0C at night in northern areas.
The current conditions indicate that water levels and outflows will continue to decline at most locations. The Trent Severn Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.
Haliburton and Northern Areas
The Halliburton’s reservoirs are below average and are levelling off. The present snowpack is 50 percent of the average for this time of year. Due to the reduced snowpack and below normal precipitation in the month of March, ongoing water operations are reducing the outflows from the reservoirs based on the remaining projected snowmelt runoff.
Kawartha Lakes and the Otonabee River
The Kawartha Lakes are below or close to average and are levelling off. Flows on the Otonabee River are low and below than average for this time of year and low.
Rice Lake and the Lower Trent
Rice Lake water level is close to average and levelling off. Flows on the Lower Trent River are below average and declining.
Lake Simcoe water levels are above average and close to the rule curve. Lake Simcoe outflows are reduced. Flows on the Severn River are close to average and are declining.
