Water Management Update – Apr9/19

From the TSW:

Water Level Management Update – Tuesday, April 9, 2019


The five day forecast suggests 5 to 10 mm of rainfall with no large amount on any given day. Evening temperatures are expected to drop below zero over the weekend in the Haliburton area. 


Flows and water levels are expected to increase at all locations for the rest of the week as the impacts of the rain and melting snow work their way through the system.

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.

Ice on Shorelines

The temperature variations around and above the freezing mark makes ice weak along the shoreline which is then easily broken and moved by windy conditions. The areas subject to the greatest impact are those facing the primary wind direction. In the event of strong wind conditions the public should be aware of possible onshore ice movement leading to shoreline damage. The current forecast winds are not overly high. With the warmer temperatures persisting into next week ice out should continue. 

Haliburton and Northern Areas

With the recent rain on snow event water levels and flows are rising rapidly in northern areas. Most lakes on the Gull River and Burnt River systems remain below average but are rising due to the onset of the melt. Lake levels are monitored daily and assessed in relation to estimated runoff amounts. The flows on Gull River and Burnt River remain above average due to the recent rain on snow event. Flows on both rivers are anticipated to increase.
