Highlights for the Reservoir Lakes area:

Weather

The five day forecast suggests 5 mm. Air temperatures are forecasted stay above  0°C across the entire Trent and Severn Watersheds.

Outlook

Rainfall amounts yesterday varied from 10 to 30 mm with the highest amounts being recorded in the Black River watershed. 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 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 still remain below average for this time of year but significant increases are anticipated. Lake levels are monitored daily and assessed in relation to estimated runoff amounts. The flows on Gull River and Burnt are now above average due to yesterday’s event. Flows are on both rivers are anticipated to increase.
