The wind blowing across Lake Simcoe was strong. The waves were not over the dock, so I would estimate at about 18 inches.
While visiting Toronto, my neighbour phoned to tell my dock has been washed off the base and was stuck under HIS dock - and the waves were five feet high. Five feet high? Really?!
I got home and sure enough an entire top section of my dock was missing, a quarter of it retrievable, and the rest - vanished into the bowels of Lake Simcoe.
The stone path from the patio to the water was also somewhat washed away.
Living on the water has a whole new set of issues.
