Lake Champlain is at flood stage. Currently an area of the bike path is underwater. This happens every few years, especially at this spot in front of the benches. It's the path's low point, often only three feet above the normal waterline. I'm sure that part of Green Up day will be spent clearing the debris from the path once the water recedes.
I love this view. Both left and right sections are underwater, creating an "island" effect with the lake water in the background. The rocks are the border line between path and lake.
