The Ministry of Natural Resources and Forestry – Parry Sound District is advising area residents that a Watershed Conditions Statement – Water Safety is in effect for the District
which includes the District Municipality of Muskoka, the Territorial District of Parry Sound and a north-west portion in the County of Haliburton.
Increasing water levels and flow conditions, typical of this time of year, exist throughout the area and residents are reminded to keep a close watch on conditions, regularly check for updated messages and exercise caution near fast-moving rivers and streams. Residents and those visiting the area are advised to be aware of current watershed conditions, exercise caution while around water bodies and maintain close supervision of children and pets.
With existing conditions and forecasts flooding is not expected but those affected by high water levels in the past are advised to take necessary action to secure any vulnerable property in close proximity to rivers and lakes.
MNRF is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate.
TECHNICAL INFORMATION
Description of Weather System
Unseasonably mild temperatures have been occurring and are forecasted to continue into next week. The weather forecast for the five day period beginning March 11th is for above seasonal temperatures in the 6 -10 degree Celsius range for daytime highs and temperatures in the low single digits at night. Forecasted rainfall amounts range from 10 to 25mm.
Description of Current Conditions
The snow pack water content is currently normal for this time of year. Above seasonal temperatures and rain forecasted into early next week will continue to melt the snow pack and runoff from the melt will begin to enter local water courses resulting in higher river flows and rising lake levels. If we experience prolonged mild temperatures as forecasted in the absence of significant rainfall it should result in a slow melting of the snow pack and a steady and predictable rate of rise in local lakes and rivers.
During this time of year we can expect higher and faster flowing water in most watercourses.
Slippery and unstable banks and extremely cold water temperatures can lead to very hazardous conditions around any water body.
