Quoth the wikipedia;
"A team from the U.S. Army Corps of Engineers dammed the falls in June 1969 in order to clear rock from the base of the falls. Rockslides had caused a significant buildup of rock at the bottom of the American side of the falls, and the engineers were to clean up the rock and repair some faults to prevent eventual erosion of the American side of the waterfall. A temporary dam was constructed to divert the flow of water to the Canadian side; the dam measured 600 feet (180 m) across and was made of nearly 30,000 tons of rock. The engineers cleared the rock debris and tested for safety, finishing the project in November of that year. Water flow was restored on November 25, 1969."
