It is possible to create a temporary stone and earth dam slope (clearly visible in the photo on the right) 5. While the waterfall "Horseshoe" received an additional amount of water, the US Army Corps of Engineers studied the riverbed and correcting mechanical defects, which otherwise would only lead to further acceleration of erosion and retreat of the falls.
