The recent rain combined with the melting snow and ice has caused extreme flooding especially around rivers such as the north and south branches of the Muskoka river. The water is now exceeding the capacity of the dams in the Huntsville area. Many road closures and evacuations are taking place. Water levels are up very high on the big three lakes so you may want to have someone check on your cottage and docks. Here is a video taken around Bracebridge that shows the massive volumes of water. thanks to districtmediadesign.
