The water level in Lake Simcoe is expected to continue to slowly drop through the week.  There continues to be an increased potential for flooding of low-lying lands adjacent to the lake.   The risk of flooding will be increased in localized areas due to wave action from winds.

The high lake levels will also continue to impact the dykes in the polder areas.  Polders are low-lying lands adjacent to bodies of water and protected by dykes.
