Both of these images were taken from, as near as was possible, the same place.  The top image, taken about a year ago (January 2011) after the snow thawed; the bottom image, taken a few days ago (January 2012). To give some sort of scale to the differences in the water levels, I’m just under 6′ and I can stand fully upright under the left most arch, which, as you can see, is almost fully submerged in the top image.
