Water Management Update – Feb7/19

From the TSW:

Water Management Update – Thursday, February 7, 2019


The forecast for Thursday and Friday of this week suggests a low precipitation event of 5 to 10 mm combined with plus temperatures approaching 10 degrees.  The warm up and cool down period is estimated to be approximately 12 hours in length.  The brief warm spell is followed by more seasonal temperatures.   


Rainfall and warm temperatures earlier in the week have for the most part primed the snow to be ready to run off.  Water levels and outflows are expected to increase at all locations due to the precipitation and snow melt. Trent Severn Water Management team will be active and the changing conditions will be closely monitored.  Any watershed conditions updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district. 

Haliburton and Northern Areas 

All reservoir lakes remain at their respective winter set dam configuration. Water levels on the lakes in general are near average and are levelling off after the recent rain on snow event.  Flows on the Gull and Burnt Rivers are near average for this time of year and will likely increase with the rainfall and warm temperatures.

Kawartha Lakes and the Otonabee River

The levels on the Kawartha Lakes are slightly above average due to the recent rain and snow melt event. Flows on the Otonabee River are above average for this time of year.  Flows will likely remain higher as a result of the event and the continued need to drawdown the Kawartha Lakes.  

Rice Lake and the Lower Trent

Rice Lake water level is above long term average and is decreasing. Flows on the Lower Trent River are above average as a result of the recent event.  

Severn River

Lake Simcoe water levels are near average, and are increasing due to the recent event; outflows from Lake Simcoe have been increased. Flows on the Black River are about average and increasing. Flows on the Severn River are about average and will continue to increase with additional discharge from Lake Simcoe and additional flows generated by the upcoming event.
