Water Management Update – Apr12/18

The weather forecast indicates that we may see changing water levels and river flows over the next few days. 

From the TSW:

The 7 day forecast suggests significant amounts of precipitation reaching 90 mm of rain and with mixed precipitation and below 0C temperatures at night in northern areas. 

The recent snow and rain amounted to an average of 25 mm of precipitation 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 Haliburton reservoirs are below average. The snowpack remains 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 and Burnt Rivers are below the average for this time of the year.
