Highlights from the Update for the Reservoir Lakes area:

Weather

The 5 day forecast suggests no precipitation. Air temperatures are forecast to rise towards the end of the week with above 0°C at night in northern areas

Outlook

The recent event amounted to close to 100 mm of mixed precipitation and solid accumulation across the TSW watersheds resulting in increased flows and water levels at most locations. The current forecast indicates that water levels and outflows will continue to increase 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.

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 suggests that these conditions are probable if the winds are high. 

Haliburton and Northern Areas

The Halliburton’s reservoirs are below average and lake levels, increasing or levelling off. The snowpack increased as a result of the recent lower than normal seasonal temperatures and solid precipitation events. Lake levels are monitored daily and assessed in relation to estimated runoff amounts, however they are susceptible to changes in response to the future precipitation amounts. The flows on Gull River are on average and Burnt River are below the average for this time of the year.
