Water Management Update – Apr11/19

From the TSW:

Water Level Management Update – Thursday, April 11, 2019


The five day forecast suggests 30-45 mm with air temperatures reaching double digits in the Halliburton areas.


With onset of the snowmelt and forecasted amount of rain coupled with warm temperatures  flows and water levels are expected to increase at all locations 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 and the onset of the melt are rising rapidly in northern areas. Snow amounts are still remaining above average for this time of the year in the most northern areas of the Gull River system. 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 remain above average due to the snowmelt. Flows are on both rivers are anticipated to increase.
