In 1969 Niagara Falls was turned off - images

For six months in 1969, Niagara Falls were turned off as the Army Corps of Engineers conducted a geological survey of the falls’ rock face, concerned that it was becoming destabilized by erosion and might not remain as a viable tourist attraction.

During the study period, the dried riverbed and shale was drip-irrigated by long pipes stretched across the gap, to maintain a stabilizing level of moisture. Workers cleaned the former river-bottom of unwanted mosses and drilled test-cores in search of instabilities, a temporary walkway was installed a mere twenty feet from the edge of the dry falls, and tourists were able to explore this otherwise inaccessible and hostile landscape.

The Engineers determined that the expense of re-engineering the rock face for greater stability was greater than the potential benefit, even though the study did find a great deal of instability in the American Falls.

Fascinatingly, the Corps’s excursion into waterfall surgery, though framed in terms of “stability” and “collapse”, was essentially for purely aesthetic benefit: the primary worry which prompted the study was the possibility that the Falls would collapse sufficiently to no longer contribute to Niagara Falls as a tourist attraction.
